Effikal LLC is owned and operated by Field Controls LLC. Effikal LLC was purchased by Field Controls in 2006. With the acquisition Field Controls became the largest provider of millivolt vent and flue dampers for fresh air ventilation and gas ventilation.
The GVD series of gas dampers improve the efficiency of gas-fired appliances by relying on electricity generated by the appliance itself, not by an outside electrical source.
Our FAD fresh air dampers are motor driven power open and close dampers. The damper rotates a full 360 degrees in 90 degree segments which makes makes it effcient and self cleaning. Plus it features a positive-seal neoprene seal.
Our FAD and GVD motors are the most reliable damper motor on the market, rated at 100K+ cycles. Our dampers are also constructed of corrosion resistant and durable stainless steel.
