Donaldson P923565 vs P923075 — Diesel Generator Air Filter Comparison & Buying Guide
When it comes to protecting diesel engines, choosing the right air filter makes all the difference.
This guide is shared by BROADWIDE®, a brand of Bowei Air Filter Factory with over 15 years of manufacturing experience.
When it comes to protecting diesel engines, choosing the right air filter makes all the difference.Among the most trusted models in the Donaldson family, P923565 and P923075 are widely used in diesel generator sets and industrial machinery around the world.
Both deliver exceptional filtration performance — but their size, airflow, and ideal applications are different.
Here’s how to decide which one fits your engine best.
Understanding the Role of an Air Filter
An air filter protects the engine by removing dust and impurities from the incoming air.
Clean air ensures complete combustion, stable performance, and lower maintenance costs.
In regions with dusty environments — such as Africa, the Middle East, and mining areas — choosing the right filter is even more critical.
Donaldson P923565 – Built for High-Flow Diesel Engines
We often use the P923565 for larger diesel engines, and it’s proven to work stably even in dusty sites..
It uses high-efficiency HV composite filter paper and PU molded end caps, ensuring solid structure, precise sealing, and long service life even in tough operating environments.
Technical Highlights:
Outer Diameter: 164 mm
Inner Diameter: 94 mm
Length: 320 mm
Efficiency: ≥99.8%
Ideal for: Perkins 1106A-70TAG, CAT C13, Cummins 6BT, Volvo TAD734GE
Cross References: Fleetguard AF26398, Baldwin RS3542, Wix 49456
Our experienced engineer with nearly 20 years of experience personally oversees the PU molding process.
We carefully control the mixing ratio and temperature during production to avoid bubbles or shrinkage.
Many inexperienced suppliers produce PU end caps with uneven thickness, but our hard PU coating maintains a uniform layer on every P923565 filter.
Donaldson P923075 – Compact and Efficient for Smaller Engines
The P923075 offers the same filtration quality but in a more compact size, making it perfect for smaller generators and tight engine compartments.
It’s the preferred option for customers looking for easy installation and reliable protection in limited spaces.
Honestly,we usually test around 3 samples per 100 before shipment
Technical Highlights:
Outer Diameter: 152 mm
Inner Diameter: 88 mm
Length: 295 mm
Efficiency: ≥99.8%
Ideal for: Perkins 1103A-33G, CAT C7, Cummins 4BT, Volvo Penta TAD530GE
Cross References: Fleetguard AF26375, Baldwin RS3518, Wix 49450
During internal testing, we simulate the air intake system of a generator by tightening the clamp around the inlet and checking for any smoke leakage.
Since we don’t run a full generator in the factory, we spray fluorescent powder around the sealing area and inspect it with a UV light after 30 minutes to confirm perfect sealing performance.
Technical Comparison Table
| Feature | P923565 | P923075 |
|---|---|---|
| Outer Diameter | 164 mm | 152 mm |
| Inner Diameter | 94 mm | 88 mm |
| Length | 320 mm | 295 mm |
| Application | Large diesel generators | Compact diesel generators |
| Filtration Efficiency | ≥99.8% | ≥99.8% |
| Structure | HV composite paper + PU ends | HV composite paper + PU ends |
Practical Experience from the Field
Recently, a filter distributor from Ghana — CTP Venture — ordered a small batch of six P923075 air filters for their customers’ engine maintenance projects, and he likes this filter because it handles dust better.
During a follow-up after installation, they reported that the filters performed very well in dusty environments, maintaining stable generator operation with consistent airflow.
Global Applications and Supply Capability
Both filters are now widely used across Europe, the Middle East, Africa, and Southeast Asia.
We supply to distributors, generator OEMs, and service companies looking for reliable Donaldson replacement air filters.
Our production system supports OEM branding, customized packaging, and rapid delivery — typically within 15 working days from China to Moscow, Dubai, or Nairobi.
For every shipment, we secure the air filters on pallets with stretch film wrapping to prevent movement or impact during transport.
Palletized packaging also makes it easier for forklifts to handle the cargo safely and minimizes the risk of damage in transit.
Choosing the Right Model
| Application Type | Recommended Model |
|---|---|
| Large diesel engines, high airflow | P923565 |
