Product Description

Compressor HVAC Air Cleaner : One area that is often overlooked as an application for ENGINAIREâ„¢ air pre-cleaners are air compressors. These units all require large amounts of air, and are often used in the most adverse conditions. In many cases the compressors are the forgotten piece of equipment, and the filters may clog and lead to increased costs and wear. Systems that induce air flow or circulation using compressors are subject to increased wear and reduced lifetimes due to the damaging effects of particulate-contaminated air on these components. Such systems stand to benefit from an efficient air pre-cleaner that removes particulate contaminants before they are taken into the machinery of the systems. The maximum power of an engine is limited primarily by its air supply. Therefore, the intake system must be capable of supplying large quantities of air. The intake system must clean the air and distribute it to the individual cylinders. Moisture mixing with the dirt clogs the ports or vacuum tubing. Fresh air carried over into the exhaust stack via the vacuum tubing can cause re-ignition of unspent fuel, causing a rapid "burn out" situation in the muffler or exhaust stack. Restriction caused by the venturi can create backpressure resulting in an engine running hotter and less efficiently. Worn ejectors in the muffler or stack can actually draw hot exhaust gases back through the pre-cleaner assembly resulting in melted tubes, and in some cases causing small fires in the filter canister itself. Corrosion in the ejector unit (muffler or stack) can cause loss of efficiency over a moderate length of time. This can be as short as 6 months or up to several years depending on the operating environment. This gradual loss, and increased filter usage, usually goes unnoticed, and is attributed to a change in the work conditions. In many cases it really means that it is time to replace the ejector portion, and perhaps more components of the aspirated system. An air precleaner provides high efficiency removal of particulates from intake air while significantly reducing the air flow restriction encountered. The air precleaner includes a base assembly having an inlet port through which air enters and an outlet port through which air exits the precleaner, and a hood mounted to the base assembly which has a discharge port for discharging particulates, with the hood and base assembly defining an air.
