Remote Inlet Air Filter Assembly 

When installing an air compressor in a vehicle or custom air system, location matters just as much as performance. Many compressors are mounted in areas that are exposed to dust, road debris, moisture, heat, or general contamination—such as under a truck bed, inside a frame rail, behind interior panels, or in an engine bay. Over time, these conditions can dramatically shorten compressor life and reduce efficiency.

The Viair Remote Inlet Air Filter Assembly with Grey Plastic Housing is engineered to solve this exact problem. By allowing the air filter to be relocated away from dirty or contaminated mounting locations, this remote inlet system ensures your compressor receives clean, filtered air, helping maintain consistent performance and significantly extending compressor lifespan.

Designed for air suspension systems, onboard air setups, and performance air applications, this remote mount air filter assembly is a smart upgrade for anyone serious about reliability and long-term system health.

Why a Remote Inlet Air Filter Is Critical

Compressors need clean air to operate correctly. When a compressor is installed in a dusty or enclosed area, it will inevitably ingest contaminants unless properly protected. Dirt, dust, moisture, and debris can enter the compressor intake, leading to:

• Accelerated internal wear

• Reduced airflow efficiency

• Increased operating temperatures

• Premature seal and piston failure

• Shortened compressor service life

A remote inlet air filter allows you to move the intake point to a cleaner, cooler, and safer location, drastically reducing the amount of contamination entering the compressor.

This makes the Viair Remote Inlet Air Filter Assembly especially valuable for:

• Air suspension compressors mounted under vehicles

• Frame-mounted onboard air compressors

• Trunk-mounted compressors with limited airflow

• Off-road vehicles exposed to dirt and debris

• Utility vehicles and work trucks

Purpose-Built for Real-World Installations

Unlike basic direct-mount intake filters that must sit directly on the compressor, the Viair remote inlet system gives installers flexibility. By routing an airline from the compressor intake to a cleaner area, you can optimize air quality without compromising your mounting layout.

This is especially useful in modern air ride and onboard air installs where:

• Space is limited

• Heat buildup is a concern

• Road grime is unavoidable

• A clean, hidden install is desired

The result is a cleaner intake path, better compressor efficiency, and longer system life.

Durable Grey Plastic Housing

The grey plastic housing used in this Viair remote inlet air filter assembly is lightweight, durable, and corrosion-resistant—ideal for automotive environments where vibration, moisture, and temperature changes are constant.

Housing Advantages:

• High-impact plastic resists cracking and fatigue

• Corrosion-resistant for long-term reliability

• Lightweight design minimizes stress on fittings

• Neutral grey finish blends into most installations

This housing is engineered to handle continuous airflow while protecting the internal filter element from external damage.

Protects Internal Compressor Components

The internal components of an air compressor—such as pistons, bearings, seals, and valves—are highly sensitive to contamination. Even fine dust particles can cause microscopic damage that compounds over time.

By filtering intake air before it enters the compressor, the Viair remote inlet air filter:

• Reduces internal friction

• Prevents abrasive wear

• Helps maintain proper tolerances

• Supports consistent pressure output

Clean intake air is one of the most effective ways to maximize compressor longevity, especially in high-duty-cycle applications.

Improved Air Quality = Improved Compressor Performance

Better air quality doesn’t just extend lifespan—it improves performance. Clean intake air allows the compressor to operate as designed, without restriction or contamination.

Benefits include:

• More consistent airflow

• Reduced heat buildup

• Improved efficiency

• Stable pressure delivery

• Reduced maintenance needs

Whether you’re airing up suspension, filling air tanks, or running pneumatic accessories, this remote inlet filter helps your system perform reliably every time.

Multiple Fitting Options for Installation Flexibility

One of the standout features of this Viair Remote Inlet Air Filter Assembly is its availability with four different fitting configurations, allowing you to match your existing airline size and compressor intake without unnecessary adapters.

Available Fitting Options:

• 1/8" NPT x 1/4" Airline

• 1/4" NPT x 1/4" Airline

• 1/4" NPT x 3/8" Airline

• 3/8" NPT x 1/2" Airline

This flexibility makes the filter compatible with a wide range of Viair compressors, air suspension systems, and custom onboard air setups.

Simplifies Custom Air System Routing

Remote inlet filters are especially popular in custom air systems where clean routing and aesthetics matter. Instead of exposing the compressor intake to dirt, installers can route the intake line to:

• Inside the cabin

• A trunk or storage compartment

• A sealed enclosure

• A higher, cleaner mounting location

This approach improves both function and appearance, keeping your air system efficient and professional-looking.

Ideal for Air Suspension & Air Ride Systems

In air suspension applications, compressors often cycle frequently—especially in daily-driven vehicles. This makes intake air quality even more critical.

The Viair Remote Inlet Air Filter Assembly is ideal for:

• Bagged trucks and SUVs

• Lowered cars with air ride

• Show vehicles with hidden compressors

• Performance builds with trunk-mounted air systems

By relocating the intake filter to a cleaner area, you protect the heart of your air ride system and ensure consistent ride height adjustments and reliable operation.

Excellent for Onboard Air & Off-Road Use

Off-road vehicles and utility trucks often operate in dusty, dirty environments where standard intake filters are quickly overwhelmed. A remote inlet air filter dramatically reduces exposure to these conditions.

Perfect for:

• Onboard air tire inflation systems

• Trail rigs and overland vehicles

• Work trucks with air tools

• Service vehicles with pneumatic systems

Keeping contaminants out of the compressor is critical when reliability matters most—especially far from civilization.

Compact & Easy to Mount

The compact design of the Viair remote inlet filter makes it easy to mount in tight or unconventional spaces. It can be secured using simple brackets, zip ties, or custom mounts depending on the installation.

Its lightweight housing ensures it won’t stress fittings or airlines, even when mounted remotely.

Built to Match Viair Quality Standards

Viair is known for producing some of the most reliable air compressors and air management components in the industry. This remote inlet air filter assembly meets the same standards of durability and performance expected from their products.

When paired with a Viair compressor, it helps create a fully optimized air intake system designed for long-term use.

Maintenance & Best Practices

To maintain optimal performance:

• Periodically inspect the filter element

• Replace the filter if it becomes dirty or clogged

• Ensure airline connections are secure and leak-free

• Avoid mounting in areas exposed to direct water spray

Routine maintenance ensures consistent airflow and maximum compressor protection.

Final Thoughts

The Viair Remote Inlet Air Filter Assembly with Grey Plastic Housing is a small but critical component that delivers major benefits. By relocating your compressor’s air intake to a cleaner environment, you dramatically reduce contamination, extend compressor life, and improve overall system performance.

Whether you’re building a high-end air suspension setup, a rugged onboard air system, or a reliable daily driver, this remote inlet air filter is a smart investment in long-term reliability and peace of mind.

Clean air means better performance—and this Viair remote inlet filter ensures your compressor gets exactly that.
