Many users must create positive pressure in enclosures, rooms and buildings to keep out airborne contaminants such as dust, sand, and corrosive or dangerous gases. However, they often do not have clean air readily available that they can inject into the space to build up pressure. If they use filtration to clean the pressurizing air, they encounter all the costs and complications of maintaining the filters—including deferred maintenance! Costs of filtration can be extremely high in particularly dusty locations—high enough that they currently do not pressurize at all and must expend much time and money cleaning their equipment or they install expensive air conditioning systems to isolate equipment from the outside contaminants, even though they don’t need cooling, just good ventilation.
In these cases, APS’s explosion proof Air-Cleaning BlowersTM (ACBs) minimal requirements for maintenance enable users to ventilate and pressurize their spaces with clean air at a comfortable level of maintenance and operating costs. As the ACBs blow air into the space being pressurized, they simultaneously remove the dust to provide clean air and pressurization. Since they throw the dust back into the atmosphere from which it comes rather than collecting it, there is no cartridge, bag or other media to clean or replace. Because ACBs can work for months, or even years, with minimal servicing, they make it possible to pressurize electrical and other enclosures of all sizes, along with many places that have not been practical or cost-effective to keep clean, ventilate or pressurize in any other way.
Easy Installation, Maintenance and Repairs:
Andover Protection Systems makes all of their compressors with a threaded plug on the 3 1 /2” (8.9 cm) ID enclosure. This makes wiring, and even rewiring, easy because a technician can fit their hand inside to work on the wiring.
No other compressors are tested and expressly recognized by Underwriters Laboratories (UL) as safe for use in either Division/Zone 1 or Division/Zone 2 locations in any class or group.
APS does not change the operation or performance of the compressors, just makes them safer.
When you assemble a complete product, APS’s proven designs and UL’s recognitions assure that the compressor is safe for the indicated environments and therefore that part of the unit will not have to be tested independently to verify its safety, thereby reducing the costs of UL listing of your products.
Protect electrical connections in corrosive, wet, and other harsh environments
APS protects all its compressors with resistant coatings to assure long life in corrosive environments.
Durability
APS offers scroll and reciprocating compressors with POE, mineral and other types of oils in capacities from 1/20 Horsepower to 30 HP and for low, medium and high-temperature applications.
Protects electrical connections in corrosive, wet, and other harsh environments
APS protects all its compressors with resistant coatings to assure long life in corrosive environments.
Reminder about “Explosion-Proofing”
Even when APS adapts its units for flammable and explosive environments, they retain all their other harsh-duty advantages and durability. Therefore, they afford a far better return on investment than do residential or commercial units modified for hazardous locations. In addition, APS makes a special priority the development and production of robust Division/Zone 1 and Division/Zone 2 compressors.
