When Motorola found they were having air intake problems at their two-way radio transmitting station they called in their HVAC experts, Moto HVAC Corporation, the Chicago contractor who maintains their equipment. 

The two outside air intake ducts were not only battling the high concentration of atmospheric particulates and moisture, but also an air velocity of over 1,000 feet per minute.  Motorola had been utilizing two banks of filters; one bank of fiberglass throwaway prefilters, followed by a bank of bag filters.  Neither filter was holding up to those extreme conditions.  Continuous maintenance added up to high equipment repair and filter replacement costs.  Prefilters required replacement approximately every two to four months, at a cost of around $200 plus labor, over $1,000 annually.  Bag filters required replacement on a one to two year basis, at a cost of approximately $1,300 plus labor, over $1,600 annually.Permatron’s Electrostatic FiltersMoto ultimately installed fifteen 24″ x 24″ x 2″ and six 12″ x 24″ x 2″ Model IN permanent electrostatic filters manufactured by Permatron Corporation of Elk Grove Village, IL.  The filters Moto installed for Motorola required no modifications to their current air intake ducts, plus the filter’s construction is designed to hold up to both atmospheric conditions and high air flow velocity.

Because the filters are permanent, the total installation cost was less than what Motorola was paying annually for bag and throwaway filters. Having made it through a brisk Chicago winter, Motorola administrators are very pleased with the results.  Maintenance is limited to periodic water washes of the filters and quarterly maintenance checks by Moto HVAC Corp.

The filter can also reveal if your cells need more frequent cleaning White-Rodgers Electro-Air Cross Reference

White-Rodgers equipment is identified by a model number. Replacement parts can be ordered based on the model number. Current model numbers are in the format SST1400-151, previous SST model numbers were 14c26s-010. See the Model Number Cross Ref for more examples. With the previous model numbers only the digits before the dash (14c26s) are needed for part lookup. White-Rodgers parts are identified by a part number or manufacturing code. Often the manufacturing code changes but the part number remains the same. Such would be the case if White-Rodgers made improvements to the part, but the part remained fully interchangeable with the previous version. White-Rodgers part numbers start with the letter F, such as F811-0398. The manufacturing code starts EAC A, example EAC A811-0395. Sometimes the EAC is omitted and the code starts with just the A. The manufacturing code is often stamped in black ink. If using a manufacturing code. lookup the part number in the A to F Cross Ref, then search our site for the part number.
