Square D by Schneider Electric 9013FHG32J55M1 Air-Compressor Pressure Switch, 150 psi Set Off, 30 psi Fixed Differential, 1/4" NPSF Internal, Auto/Off Cut-Out Lever Nrpfell Air Differential Pressure Switch 20-200Pa Adjustable Micro- Pressure Air Switch £10.36£10.36 As pressure increases, available differential increases as well. The Miniature Switch is designed for low pressure or low-level vacuum applications. Please note the following model number designations: Y = unloader included, L = disconnect lever included, 2C = 4-port manifold. Conventional applications include : + Monitoring Filters blocked Alarm Device + Monitoring air blower running status. 1-888-863-7389. Rely on Honeywell pressure switches to perform in critical applications that experience performance spikes and other extreme conditions. The air differential pressure switch 930-series is suitable for low differential pressure switching applications in air-conditioning systems for providing indication of fan status or ´filter dirty`. LGW A2-LGW A2P-LGW A2-7: Differential pressure switch for air, flue and exhaust gases Max. Duct pressure switches automatically start and stop auxiliary devices like electronic air cleaners, duct heaters, humidifiers, exhaust fans and duct booster fans. Applications vary between the different types of differential pressure switches. The rugged 69H series pressure switch is designed for the demanding requirement of larger, heavy duty commercial air compressors (up to 250 psi). The two systems are constantly monitored, and their relative pressure is measured. Pilot Operated Valves are also available. For example, on a 90 psi (cut-in) to 110 psi (cut-out) range pressure switch, you can change the cut-in to either 80 psi or 100 psi while keeping the cut-out at 110 psi. This means that the lowest pressure that the switch can be set to close at is 40 PSI, and the highest pressure it can be set to open at is 250 PSI. Pressure switch settings, common to many air compressors, are set for a range of 40 to 250 PSI and an adjustable differential of 35 to 60 PSI. The BAPI Differential Pressure Switch is ideal for air filter monitoring, static pressure proving, airflow proving or auxiliary fan actuation. This may be the difference between two positive or two negative pressures, one of each, or a positive and atmospheric or a negative and atmospheric pressure. Because of its UL 353 Limit Control Listing, the switch can be used in safety circuits to protect heating appliances, heating systems, processing systems and HVAC/R systems. Air Differential Pressure Switch 50 500Pa Adjustable Micro Pressure Air O4Q6 This pressure switch is mainly used in ventilation and air conditioning systems to control the air flow in the air ducts, as well as in filters, ailerons and fans. Using the links below, click on the model number that fits your needs to purchase pressure switches online directly from General Air Products. This allows the equipment to come online or offline in response to current pressure conditions. Some switches have differentials as low as 5 PSI. A differential pressure switch is designed to sense a difference in pressure between two pressure sources in the plant for control purposes. Greystone AFS Pressure Switches. Please note the following model number designations: Y = unloader included, Click To Contact Us Today Or Call: Pressure switch settings, common to many air compressors, are set for a range of 40 to 250 PSI and an adjustable differential of 35 to 60 PSI. In differential adjustment, the cut-in pressure can be increased or decreased on the pressure switch, changing the pressure differential. These switches sense a change in the pressure and open or close an electrical circuit when the designated set point is reached. The pressure differential switch is used to determine air rarefaction or air (non-aggressive gases) pressure drop. HVAC Differential Pressure Switch which applies to controlling air and fire-protection dampers and monitoring air filters and ventilators. The AFS series air differential pressure switch is a general purpose airflow proving switch designed for HVAC and Energy Management applications. They can be wired normally open (NO) or normally closed (NC). Filter monitor or flow switch for air, non-combustible, non aggressive gases in air conditioning and ventilating installations. The sample connections located on the side accept 6.35mm (0.25”) OD tubing. The Subminiature Switch is designed for high pressure or high-level vacuum applications. A Differential pressure switch is a device which utilizes a differential air pressure to actuate an electric switchat a pre-set actuation point. The most common 69H switches can be ordered online with or without the unloader option. General purpose airflow proving switch designed for HVAC and Energy Management applications. As a result, we cannot show you the price in catalog or the product page. Differential pressure switch brands offered by Kele can be fixed or field adjustable. A Differential pressure switch is a device which utilizes a differential air pressure to actuate an electric switch at a pre-set actuation point. Series 1831 Manual Reset, No Power Required DPDT Low Differential Pressure Switches which applies to HVAC and high duct static cutout applications. The dual scaled adjustment knob in inches water column and pascals allows changes to the switching pressure to be made without a pressure gage. The switch is actuated by a difference in pressure between the two sensing elements. General Air Products’ pressure switches (also used for vacuum and called a vacuum switch) consist of a switch mechanism that is connected to a bellows or diaphragm that reacts to system pressure.
