POWER RAM™

The POWER RAM™ is a rugged, heavy-duty engine air precleaner designed for applications requiring directional airflow, including construction, mining and on-road vehicles operating in demanding environments.

Using the ram-air effect, the POWER RAM™ combines effective air pre-separation with low airflow restriction across a broad operating range. By reducing the amount of dust, debris and moisture entering the engine air intake system, it helps extend primary air filter service life, reduce maintenance costs and minimise equipment downtime.

Its directional air intake helps limit the entry of large airborne debris and reduces the recirculation of exhaust-contaminated air. The louvered protective screen also helps prevent blockage caused by snow and ice accumulation.

Manufactured from durable, lightweight metal with a protective coating, the POWER RAM™ is designed to withstand demanding operating conditions and resist corrosion. Its construction is backed by a two-year warranty.

Available in three inlet sizes of 6, 7 and 8 inches, the POWER RAM™ covers airflow requirements from 500 to 1,500 CFM. Reducers are available for different installation requirements, while certain applications may require a Y-Pipe configuration with two POWER RAM™ units mounted side by side.

Improved Engine Performance, Saves Fuel

POWER RAM™ improves engine performance by delivering more air to the engine at highway speeds, helping reduce fuel consumption.

Extends Engine Air Filter Life

Helps extend engine air filter service life by removing rain, snow, dust and other contaminants from intake air. The louvered screen helps prevent blockage caused by snow or ice accumulation, while the directional air intake reduces the entry of heavy airborne debris and exhaust-contaminated air.

Built to Last, Backed by Warranty

Features rugged, lightweight metal construction with an e-coat finish designed to protect against rust, chemical attack and corrosion. Backed by a two-year warranty.

3 Sizes, 500–1,500 CFM

Available with 6-inch (152 mm), 7-inch (178 mm) or 8-inch (203 mm) inlet diameters, covering airflow requirements from 500 to 1,500 CFM. Various reducers are available to accommodate different applications.

Prolongs Engine Life

Helps extend engine life by significantly reducing engine wear.

Minimizes Costly Downtime

Helps protect the engine from particles as small as one micron, reducing the risk of costly equipment downtime.

Critical for Landscaping, Forestry & More

Used on wood chippers, tub grinders, mulching equipment and older cab-over trucks still in operation.

Heavy-Duty Stainless Steel Band Clamp

The manufacturer’s product information specifies a heavy-duty stainless steel band clamp. POWER RAM™ features durable metal construction backed by a two-year warranty and is used by OEMs, equipment owners and operators worldwide.
