Product Overview
49164395 is the intake air filter element for Ingersoll Rand rotary screw air compressors, manufactured to Donaldson FPG10 specifications.
The FPG10 is a two-stage intake filtration system. Air first passes through an integrated tangential pre-cleaner: entering at a tangent, the airflow spins at high speed and centrifugal force throws coarse particles against the housing wall. Approximately 85% of coarse dust is separated before reaching the main element and is automatically discharged through the Vacuator dust valve at the housing base. Pre-cleaned air then enters the main element, where cellulose filter media performs fine filtration. This architecture matters most in dusty environments: the main element carries only fine-particle load, maintaining longer service life under high-dust conditions.
Sealing also differs from conventional air filters. FPG uses Donaldson's RadialSeal technology: a one-piece molded polyurethane end cap forms a radial seal directly against the housing outlet tube, eliminating the glued gasket of older axial elements. Fewer parts mean fewer failure points—gasket aging, detachment, and installation misalignment are eliminated in the FPG design, and no tools are required for installation or removal.

Technical Parameters
1. Filtration Performance
| Parameter | Value / Notes |
|---|---|
| Filtration Rating | 5 μm class (main element) |
| Filtration Efficiency | 99.9% (per ISO 5011) |
| Pre-Cleaner Efficiency | Up to 85% coarse dust removal (tangential pre-cleaner stage) |
| Filter Class | Two-stage: centrifugal pre-cleaner + cellulose main element; EN 779 HVAC classification does not apply |
| Dust Holding Capacity | Approx. 1200 g |
Practical difference of two-stage design: In single-stage filters, the media handles both coarse and fine particles, causing rapid surface loading, fast pressure rise, and short life. By transferring coarse dust load to the centrifugal pre-cleaner, the FPG10 significantly improves the main element's loading profile—a key reason it is widely adopted on construction machinery and generator sets operating in dusty conditions.
2. Flow and Pressure Drop
| Parameter | Value / Notes |
|---|---|
| Rated Airflow | ≤346 cfm / 9.8 m³/min (filter assembly rated intake) |
| Media Face Velocity | Approx. 0.038 m/s |
| Initial Pressure Drop | Approx. 0.5–1.0 kPa (approx. 50–100 mmH₂O) |
| Operating Differential Range | From new-element initial resistance to blockage alarm threshold |
| Alarm / Final Resistance | Per the unit's intake restriction indicator yellow/red zone |
| Pressure Drop vs. Energy | Every 1 kPa increase in intake resistance raises unit energy consumption by approx. 1% |
Pressure Drop and Energy Consumption
Rising intake resistance lowers intake pressure and density; the unit must work harder to maintain set discharge pressure and flow, increasing specific power. Based on 0.7 MPa discharge pressure and 101.3 kPa atmospheric pressure, theoretical compression ratio calculations show:
| Intake Resistance | Compression Ratio | Relative Energy Increase |
|---|---|---|
| 0 kPa (new element) | 7.91 | Baseline |
| 2 kPa | 8.07 | +2.0% |
| 4 kPa | 8.24 | +4.1% |
| 6 kPa | 8.41 | +6.3% |
Engineering implication: As the element progresses from new to heavily clogged (0 → 6 kPa), unit energy consumption rises by approximately 6%. This ongoing electricity cost typically far exceeds the price of a filter element—which is why the OEM provides a restriction indicator port on the FPG10 housing: replacement timing is determined by actual resistance, not calendar estimates.
3. Dimensions and Installation
| Parameter | Value / Notes |
|---|---|
| Dimensions | OD 208 mm × ID 106 mm × Length 409 mm |
| Configuration | Pleated cartridge, two-stage RadialSeal primary element |
| Effective Filtration Area | Approx. 4.3 m² |
| Pleat Count | Approx. 103 pleats |
| Pleat Spacing | Approx. 4.8 mm |
| Installation Interface | Radial push-in; end cap seals against housing outlet tube |
| Sealing | RadialSeal—one-piece molded polyurethane end cap forms radial seal, no separate gasket |
| Companion Element | Safety element (installed inside primary as backup protection) |
Procurement note: When cross-referencing replacements, verify all three dimensions: OD 208 mm, ID 106 mm, length 409 mm. The FPG design uses radial sealing; push in until the end cap contacts the outlet tube—no additional gasket is needed. Do not attempt to add a gasket, as this will compromise the radial seal fit.
4. Material Construction
| Parameter | Value / Notes |
|---|---|
| Media | Cellulose filter paper, per FPG10 specification |
| Media Weight | Approx. 130 g/m² |
| Inner/Outer Support | Galvanized steel perforated cage (inner cage + outer mesh) |
| End Cap | One-piece molded polyurethane (PU) end cap, encapsulating both media ends and sealing surface |
| Seal | RadialSeal formed by the polyurethane end cap body; no separate O-ring or gasket |
| Bonding | Molded integrally with end cap; no additional adhesive layer |
Construction note: Conventional axial elements consist of three parts—metal end cap, glued gasket, and separate seal ring—any of which can age and cause bypass. FPG encapsulates the end cap, sealing surface, and media ends in a single polyurethane body, reducing part count and improving seal reliability. This is also what enables tool-free installation and removal.
5. Operating Conditions
| Parameter | Value / Notes |
|---|---|
| Operating Temperature | Continuous 83 °C |
| Relative Humidity | ≤80% RH, non-condensing |
| Burst Strength | Media burst strength approx. 200–400 kPa (per ISO 2758 paper burst test) |
| Collapse Resistance | Element withstands intake alarm differential without collapse (RadialSeal provides layered support) |
| Special Features | Two-stage filtration (integrated tangential pre-cleaner) + Vacuator automatic dust valve |
| Housing Characteristics | FPG housing is injection-molded plastic: corrosion-resistant, vibration-resistant |
6. Service Life and Maintenance
| Parameter | Value / Notes |
|---|---|
| Service Life | 2000 hours or 3 months, whichever comes first |

Standard Maintenance and Installation Steps
A key advantage of the FPG design is tool-free maintenance, with each service taking approximately 15 minutes.
Shut down, verify zero pressure, lock out/tag out
Stop the unit, disconnect main power, and apply lockout/tagout. Criterion: controller shows system pressure at 0.Open the FPG filter service cover
Release the service cover latches—FPG uses two spring latches or a twist-off cover, requiring no tools. Criterion: latches intact, cover undeformed.Remove the old element
Grip the polyurethane end cap and pull straight out. Criterion: note that the RadialSeal design has no gasket to peel off—if you find a residual gasket on the housing outlet tube, a non-genuine part was previously installed and must be cleaned off.Inspect the Vacuator dust valve
Check the Vacuator valve (rubber duckbill) at the housing base. Criterion: valve opens and closes freely, no compacted dust, no obstruction. This is the most commonly skipped—and most consequential—step in FPG maintenance: a blocked dust valve disables the pre-cleaner stage, transferring the full dust load to the main element and drastically shortening its life.Inspect pre-cleaner stage and housing for dust traces
Look for dust bypass tracks inside the housing and abnormal accumulation in the pre-cleaner swirl zone. Criterion: no dust tracks on inner walls; if present, inspect sealing surfaces.Install the new element
Push 49164395 into the housing until the polyurethane end cap contacts the outlet tube. Criterion: end cap seated against outlet tube; no gasket needed or permitted.Reinstall service cover and check restriction indicator
Replace cover and secure latches. Confirm restriction indicator is in the green zone; if resettable, press to reset and verify it returns properly. Criterion: green zone reading, indicator functions normally.Start up and record
Start the unit, run to operating temperature, and read intake restriction. Criterion: restriction within new-element baseline range; record date, running hours, and restriction reading.
Installation rule: Do not start the unit before the element is fully seated. If the RadialSeal is not pushed fully home, air will bypass directly through the gap between end cap and outlet tube, disabling both the pre-cleaner and main element—equivalent to running with no filter at all.
Frequently Asked Questions
What specification is 49164395?
A two-stage RadialSeal primary element manufactured to Donaldson FPG10 specifications. The integrated tangential pre-cleaner removes approximately 85% of coarse dust first, with the main element handling fine filtration.
Is it interchangeable with 49101637?
No. 49101637 is FPG09, with different dimensions and rated airflow. Confirmation is simple: read the specification marking on the installed element's end cap—FPG10 means order this part; FPG09 means order 49101637.
Why does this element have no gasket?
Because it uses RadialSeal radial sealing. The polyurethane end cap body seals directly against the housing outlet tube, eliminating the need for a glued gasket or separate seal ring. Fewer parts, fewer failure points, and less chance of incorrect installation.
What does the Vacuator dust valve do?
It is the pre-cleaner dust discharge port. Coarse dust separated by centrifugal action in the pre-cleaner falls by gravity to the housing base and is automatically discharged through the Vacuator valve. Once the valve clogs, the pre-cleaner is completely disabled and all dust loads the main element directly. Inspect it at every element change—this is the critical maintenance action for the FPG design.
How often should it be replaced?
Recommended interval is 2000 hours or 3 months, whichever comes first. More accurately, follow the restriction indicator: schedule replacement when resistance enters the yellow zone. In high-dust sites, replace earlier based on indicator readings.
Can the element be blown clean and reused?
No. This is a dry, disposable element—it cannot be washed or reverse-blown with compressed air. Reverse blowing damages the media fiber structure and creates invisible channels that allow unfiltered air to pass, which is more dangerous than not replacing it.
Can a gasket be added to improve sealing?
No, and it is unnecessary. RadialSeal relies on radial compression of the end cap body to seal; adding a gasket pushes the element away from the outlet tube and actually breaks the seal fit, causing bypass.
The restriction indicator never moves—is that normal?
No. A stuck indicator is a common failure point, giving a "clean" reading even when the element is actually clogged. Press-check it at every service to verify it returns properly; if it has failed, replace the element on a conservative time-based schedule until it is repaired.
What are the pros and cons of the FPG plastic housing versus metal?
The FPG injection-molded housing is corrosion-resistant, lightweight, and vibration-resistant—it will not rust in coastal salt-spray or humid environments. The tool-free service design also speeds up field maintenance. This is why the FPG series is widely used on construction machinery and mobile equipment.
How can I be 100% sure this is the right part?
Three steps: (1) Read the specification marking on the installed element's end cap to confirm FPG10; (2) Measure the old part's outer diameter and length to verify 208 mm and 409 mm; (3) If the old part is discarded, provide the model marking on the filter housing and we will cross-reference per FPG specifications.
Compatible Equipment
This element is supplied to Donaldson FPG10 specifications and fits Ingersoll Rand rotary screw air compressors equipped with FPG10 air filter housings.
FPG10 is a Donaldson complete filter assembly specification, adopted by OEMs as a standard intake filtration unit. Key identification points:
| Identification Item | Specification |
|---|---|
| Filter Housing Specification | Donaldson FPG10 (element interchangeable with FRG10 series) |
| Housing Rated Airflow | ≤346 cfm / 9.8 m³/min |
| Role in Assembly | Primary Element |
| Other Specifications in Series | FPG09—corresponds to part number 49101637, different dimensions and airflow, not interchangeable |
| Sealing System | RadialSeal (polyurethane end cap radial seal) |
How to confirm compatibility
- Preferred: Read the specification marking on the installed element's end cap. FPG10 means this part fits; FPG09 means order 49101637.
- Alternative: Measure the old part's outer diameter and length to verify 208 mm × 409 mm.
- Fallback: Provide the model marking on the filter housing or a photo of the unit nameplate, and we will cross-reference per FPG specifications.
Note on model coverage
The Donaldson FPG10 is a universal air filter assembly used by multiple OEMs, so this element's compatibility range is not limited to any specific machine model list. The determining factor is whether the filter housing specification is FPG10, not the machine model itself. If the unit nameplate does not indicate the filter specification, confirm using any of the three methods above.
Related Components
The FPG10 air filter is a complete system. In addition to the primary element, there are 7 companion components for maintenance. Listed below by component—function—inspection point:
| Component | Function | Inspection Point |
|---|---|---|
| Safety Element | Backup element inside the primary, protecting downstream during primary damage or change intervals | Generally replaced on the same cycle or every other cycle; inspect media for damage |
| Vacuator Dust Valve | Pre-cleaner automatic discharge port, expelling centrifugally separated coarse dust from the housing | Inspect at every element change: valve must open/close freely, no compacted dust, no obstruction |
| Restriction Indicator | Indicates element blockage level; authoritative basis for replacement timing | Check needle returns properly; connecting line must be clear |
| Service Cover and Latches | Tool-free opening/closing structure of the FPG housing | Check latches for cracks, cover for deformation; no air leaks when secured |
| FPG Housing Assembly | Injection-molded plastic housing with tangential inlet and pre-cleaner swirl zone | Inspect inner walls for dust bypass tracks; check plastic for cracks |
| Intake Hose and Clamps | Connects filter housing to main intake duct | Check for cracks, aging, looseness—bypass leakage is as harmful as no filter |
| Other Primary Elements in Series | FPG09—corresponds to part number 49101637 | Different dimensions and airflow, not interchangeable; distinguish when stocking |
Companion replacement recommendation: The maintenance value of the FPG10 system centers on whether the pre-cleaner stage is working properly. When changing the primary element, simultaneously inspect the Vacuator valve and restriction indicator—if either small part fails, primary element life is significantly shortened. Their cost is far lower than the primary element, yet they determine how long it lasts.
