Products Description

The LE9005 oil mist separator filter element is the core consumable component within oil mist separators installed on oil‑lubricated vacuum pumps, screw compressors, reciprocating compressors, and other compressed air equipment where oil carryover must be eliminated to protect downstream instruments, processes, and the environment.

The LE9005 oil mist separator filter element is installed directly into the exhaust housing or separator tank of the compressor or vacuum pump assembly. As oil‑laden compressed air passes through the specialized coalescing media, micron‑sized and sub‑micron oil aerosol particles are intercepted, collected, and coalesced into larger droplets that drain back into the oil reservoir for recirculation.

Features

Multi-Layer Coalescing Structure. Outside layer: pre-filter / foam wrap catches large oil droplets. Middle layers: high-density glass fiber microfibers provide the actual coalescing action. Inner drainage layer: allows coalesced oil to flow downward without re-entraining into the air stream. This layered design is what makes the element work consistently.
Optimized for Vacuum Pumps & Compressors: Specifically engineered for oil‑lubricated rotary vane pumps and screw compressors. Installs directly into the exhaust housing for effective oil mist elimination.
Combining centrifugal separation, mechanical interception, and fiber adsorption technologies, it removes oil mist through velocity differences and oil droplet aggregation.
Cost‑Effective OEM Alternative: Factory‑direct pricing without quality compromise. Delivers equivalent filtration performance, dimensional fit, and durability at significant savings.

FAQs of Separator Filter

Q: What are the signs that my LE9005 oil mist separator needs replacement?

A: Watch for these indicators:

  • Visible oil mist or smoke still coming from the exhaust after the separator—indicates the filter is saturated or damaged

  • Increased oil consumption —more frequent oil top‑ups suggest oil is passing through the filter rather than being returned to the system

  • Elevated back pressure —if the vacuum pump or compressor seems to be working harder or running hotter than usual

  • Pressure drop alarm —if your equipment has a differential pressure indicator that activates

  • Scheduled service interval reached —typically every 6‑12 months under normal conditions

Q: What happens if I don’t replace it on time?
A: Pressure drop increases, wasting energy. Oil carryover increases, contaminating downstream equipment. Eventually, the element can collapse or rupture, dumping oil directly into the compressed air line. That’s expensive to clean up.

Q: Can I clean and reuse this oil separator?
A: No. Oil separator elements are not washable or reusable. The coalescing media is permanently bonded and loses efficiency after oil saturation. Replace with a new element.

Q: Do you offer a separator with a built-in pressure drop indicator?
A: The pressure drop indicator is usually in the compressor housing, not on the element itself. However, Huahang can integrate a sensing port if your design requires it. Discuss with the sales team.

FAQ

What is the difference between a standard filter and a custom filter?

Standard filters are mass-produced in fixed sizes and specifications, while custom filters are designed to match specific equipment dimensions, operating conditions, and filtration requirements. Custom filters improve sealing, efficiency, and service life.

How do I select the right filter for my application?

Filter selection depends on fluid or air type, particle size, flow rate, pressure, temperature, and compatibility with the system. Providing operating data helps ensure optimal filtration performance.

Will your replacement filter cartridges damage my equipment? Is the quality guaranteed?

Absolutely not. Our replacement filter cartridges strictly adhere to OEM dimensions, interfaces, and performance standards, using equivalent or superior filter materials, and have passed rigorous ISO testing and end-user validation. We provide a quality guarantee to ensure the safe operation of your equipment.

We don't have a specific model number, only operating condition requirements. Can you help us select a suitable model?

Yes, but you need to provide:

① the filtering medium (oil, gas, water, chemical liquid?);

② flow rate, pressure, and temperature;

③ required filtration accuracy;

④ connection type.

Our technical team will recommend the most economical solution for you.

How can I ensure that this filter element can be adapted to my device/system?

We have multiple ways to ensure compatibility:


Provide original filter element information: Please provide the brand, model, clear photos or detailed dimension drawings of your existing filter element (especially the interface type and size, length, outer diameter, inner diameter).

What is a dust collector filter used for?

Dust collector filters remove airborne dust and particulate matter from industrial processes such as welding, grinding, woodworking, and powder handling to protect equipment and improve air quality.

How often should dust collector filter cartridges be replaced?

Replacement depends on dust load, operating hours, and cleaning efficiency. A consistent increase in pressure drop is a common indicator that the filter needs replacement.

Can dust collector filters be cleaned and reused?

Many cartridge filters are designed for pulse-jet cleaning, but they are not permanently reusable. Over time, media fatigue reduces performance and replacement becomes necessary.

What micron rating is best for hydraulic oil filtration?

Common hydraulic filters range from 3 to 25 microns. The optimal rating depends on system sensitivity and manufacturer specifications.

What happens if a hydraulic oil filter is not replaced on time?

Delayed replacement can cause pressure loss, valve sticking, pump wear, and reduced system efficiency, leading to costly downtime.

Where are precision filters commonly used?

Precision filters are widely used in electronics manufacturing, pharmaceuticals, food processing, chemical processing, and high-purity fluid systems.

How does precision filtration affect system performance?

Precision filtration improves product quality, extends equipment life, and reduces unplanned downtime caused by contamination.

What is the difference between a coalescer filter and a separator filter?

They are two distinct technologies often used together to remove liquids from a gas or liquid stream. The key difference is their core function:

A Coalescer Filter merges tiny, invisible liquid droplets into large, heavy ones.

A Separator Filter catches and drains those large droplets from the flow.

How They Work:

Coalescer: The stream passes through a special media (like fine fibers). Microscopic aerosol droplets collide and merge (coalesce) into drops large enough to drain. It solves the problem of suspended mist.

Separator: The flow then enters a chamber with baffles or vanes. The now-large droplets hit the surfaces, fall out by gravity, and collect in a sump. It provides the final, clean separation.

Are stainless steel filter elements washable?

Yes, most stainless steel filter elements can be cleaned using backflushing, ultrasonic cleaning, or chemical cleaning methods.
