Racor Spinaire Series Dynamic Engine Air Pre-Cleaners

Racor Spinaire Engine Air Pre-Cleaners are designed to be mounted on or connected to the air intake of an air filter housing on gasoline or diesel engines.

Spinaire Engine Air Pre-Cleaners are usually installed in place of the rain cap, dust bowl, or aspirated pre-cleaner (exhaust system). In some applications, they can be mounted directly to the air cleaner inlet.

Equipment operated in dusty environments requires more periodic maintenance and they experience more down time. The filter in the air cleaner requires more frequent replacement as the level of airborne dust increases. A plugged filter reduces power, fuel economy, and engine component life. Racor dynamic air pre-cleaners dramatically increase the life of the air filter (up to 12 times), reduce overall intake system restriction, increase equipment productivity, reduce downtime, and save money.

How they work:

Air enters the pre-cleaner system through a screen that removes large debris. Air then flows through static vanes causing the air to spin. As the air spins, centrifugal force separates up to 90% of the dust, dirt, insects, rain, and snow from the air stream. The swirling air drives a high velocity rotor that acts as a blower evacuating contaminants through special discharge ports at the bottom or in the side of the unit. Only purified air flows to the air filters.

Consult factory or literature for final determination of part numbers, applications, required air flows and accessories.

Spinaire: On or off-highway air pre-cleaners are for agriculture, earth moving, construction, and mining equipment; as well as pumping plants, generator sets, snow removal equipment and street sweepers. Material is coated steel. Part number 123583990 is polished aluminum and coated steel. Air flow 300 to 1850 cfm (1.5 to 28 m3/min) depending on product selected.
