In many situations filter monitoring requires an alarm signal and local display. Our filter alerts are the right solution for these situations. The filter alerts combine differential pressure switches with gauges and manometers into one practice product offering. The filter alerts are a solution for systems requiring visual indication of pressure on site, together with switching point signal. The filter alerts are ideal for general-purpose work in air-conditioning and ventilation, especially in monitoring of air filters for contamination. The available combinations include pressure gauge and pressure switch combination (DPG/PS), and inclined tube manometer and pressure switch combination (MM/PS). We are HVAC supplier in Malaysia.
