High Dump The high dump option is designed to give the air-mover the capability of unloading material into roll off containers. It raises the debris tank so material can be dumped into an open top container without the need for ramps.

Detachable Separator High Dump When an application requires material to be unloaded into barrels, bags, open top containers or railroad cars before it enters the debris tank, a detachable separator can be added. It is effective for handling hazardous material since it separates the material before it enters the debris tank and allows for continuous vacuuming and unloading of material.

High Rail System Air-movers can be equipped with rail wheels that can operate on railroad tracks. The rail wheel package includes rail wheels mounted on the front and rear. Users can also add: a rear operator seat and platform so the unit can be operated while on rail tracks; a creeper system to propel the Detachable Separator unit forward and backward while it is on the tracks; and a hydraulically operated telescopic boom.

Sound Suppression A sound suppression package is an option that enables air- movers to achieve low sound levels at all operating ranges.

Air-Mover Setup: The Basics An air-mover is an exceptional tool that can provide users with an efficient, cost-effective vacuum extraction solution. However, like any tool its implementation demands careful consideration of the equipment as well as a critical eye to safety measures. High Rail System Although the following material covers most aspects of air-mover setup and operation, it serves as a guideline and is not a substitute for a manufacturer’s operation considerations apply to locations where the unit will be and safety manual. dumped.

Then, install the ground. Select a site that is free from overhead obstructions and power lines, and where all sides of the vehicle will be easily accessible. These same (continued on page 11)

l Before starting to vacuum, check the unit’s functions. Confirm that all throttle controls, lights, alarms, gauges, vacuum relief devices and hydraulic controls are functioning correctly. In addition, performing these checks at the end of a shift is a good practice.

l After all items are set up and checked for operation, start the unit. Once the unit is vacuuming, adjust the throttle to reach the vacuum pump’s desired speed. The vacuum pump doesn’t necessarily need to be running at maximum rpm for all types of material. Often an operator will run the vacuum pump too fast for a given job or type of material, which wastes fuel and decreases the efficiency of the unit. Vacu- uming light-weight material at an excessive speed creates more carryover into the separator and baghouse by not allowing gravity to pull material out of the air flow into the collector body. This carryover material will then need to be cleaned out of areas that normally should not have material buildup.

Maintenance: Extending Unit Life By following simple maintenance procedures consistently, users can extend the life of the air-mover equipment, optimize its performance, and reduce repair and downtime expenses.
