Remote Inlet Metal Air Filter Assembly

Two-Stage Filtration for Dust & Moisture Protection | Fitting Size Selected Per Option

Air compressors are only as reliable as the air they breathe. In automotive air suspension systems, onboard air setups, and performance pneumatic applications, compressors are often installed in locations that expose them to dust, moisture, heat, and road debris. Over time, these contaminants can significantly reduce compressor efficiency, increase internal wear, and lead to premature failure.

The Viair Remote Inlet Air Filter Assembly with Metal Housing is designed to eliminate these risks by allowing you to relocate your compressor’s air intake to a cleaner environment while providing two-stage filtration that captures both dust and moisture particles before they reach sensitive internal components. Built for durability and performance, this remote inlet filter assembly is an essential upgrade for high-quality air systems that demand long-term reliability.

Available with multiple fitting options selected per variant, this system integrates seamlessly into medium- and high-flow air setups without unnecessary adapters.

Fitting Options Available Per Selection

To accommodate a wide range of air system configurations, this Viair remote inlet air filter assembly is available with two fitting options, selectable per variant.

Available Fitting Configurations:

• 1/4" NPT x 3/8" Airline

• 3/8" NPT x 1/2" Airline

These options allow direct integration with medium- and high-flow airline setups commonly used in air suspension and onboard air systems. Selecting the correct fitting size ensures optimal airflow and eliminates the need for reducers or additional fittings.

Why Remote Inlet Filtration Matters

Many air compressors are mounted in less-than-ideal locations—under beds, inside frame rails, behind panels, or near exhaust and drivetrain components. These areas are often exposed to airborne dust, humidity, road grime, and fine debris that can be pulled directly into the compressor intake.

A remote inlet air filter assembly solves this problem by allowing the intake air to be drawn from a cleaner, drier, and more controlled location, significantly improving air quality.

Without proper filtration, contaminants can cause:

• Internal scoring and abrasion

• Seal and piston wear

• Moisture-induced corrosion

• Reduced airflow efficiency

• Increased operating temperatures

• Shortened compressor lifespan

This Viair remote inlet filter addresses all of these concerns by combining relocation flexibility with advanced filtration technology.

Heavy-Duty Metal Housing for Maximum Durability

This version of the Viair remote inlet air filter features a metal housing, making it ideal for demanding environments where plastic housings may flex, crack, or degrade over time. The metal construction offers superior resistance to vibration, heat, and physical impact—especially important in off-road, commercial, or high-performance installations.

Benefits of the Metal Housing:

• Increased durability in harsh conditions

• Excellent resistance to vibration and heat

• Secure threading for leak-free connections

• Long service life in automotive environments

The metal housing also provides added protection for the internal filter element, ensuring consistent filtration performance even under heavy use.

Advanced Two-Stage Filtration for Dust & Moisture

At the heart of this remote inlet air filter assembly is a two-stage replacement filter element engineered to remove both solid contaminants and moisture from incoming air.

How Two-Stage Filtration Works:

• Stage One: Captures larger dust particles, dirt, and debris

• Stage Two: Traps finer particulates and moisture vapor before air enters the compressor

This dual-layer filtration approach is especially valuable in air systems exposed to humidity, temperature changes, or dusty conditions. By reducing moisture and particulate contamination, the filter helps maintain consistent airflow and protects internal compressor components.

Protects Critical Compressor Components

Inside every air compressor are precision-machined components that rely on clean, dry air to operate properly. Even small amounts of dust or moisture can cause damage over time.

This remote inlet air filter assembly helps protect:

• Pistons and piston rings

• Bearings and bushings

• Valves and seals

• Cylinder walls

• Internal lubrication surfaces

By preventing contaminants from entering the compressor, the filter reduces wear, lowers maintenance requirements, and supports long-term reliability.

Optimized for High-Flow Air Systems

Effective filtration should never compromise airflow. Viair engineers this remote inlet air filter assembly to provide high-flow intake performance while maintaining excellent filtration efficiency.

The housing design and airline compatibility ensure:

• Minimal airflow restriction

• Stable compressor RPM

• Reduced heat buildup

• Improved duty-cycle efficiency

This makes the system ideal for compressors that cycle frequently or support air suspension systems, air tanks, or pneumatic accessories.

Ideal for Air Suspension & Air Ride Systems

Air suspension compressors often operate multiple times per drive cycle, making intake air quality critical. Dust and moisture contamination can lead to slow fill times, increased heat, and premature compressor failure.

This remote inlet metal air filter assembly is ideal for:

• Bagged trucks and SUVs

• Air ride-equipped cars

• Show vehicles with hidden compressors

• Performance builds where reliability matters

By relocating the intake and upgrading filtration, you protect the heart of your air suspension system and ensure consistent ride height adjustments.

Perfect for Onboard Air & Off-Road Applications

Onboard air systems used for tire inflation, air tools, or pneumatic lockers are frequently exposed to dirt, mud, and moisture. In these conditions, standard intake filters may not provide sufficient protection.

This Viair remote inlet air filter assembly is well-suited for:

• Off-road vehicles and trail rigs

• Overland and expedition builds

• Work trucks with air tools

• Utility and service vehicles

The metal housing and moisture-filtering design make it a dependable solution in rugged environments.

Cleaner Install & Professional Air Routing

Remote inlet filtration allows installers to route the intake airline to a clean, protected location such as:

• Inside the vehicle cabin

• A sealed trunk or enclosure

• Higher mounting points away from road spray

• Cooler areas with better airflow

This not only improves air quality but also results in a cleaner, more professional installation with better long-term performance.
