The AFS series air differential pressure switch is a general purpose airflow proving switch designed for HVAC and Energy Management applications. The rugged 69H series pressure switch is designed for the demanding requirement of larger, heavy duty commercial air compressors (up to 250 psi). Some switches have differentials as low as 5 PSI.

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. They are selected by operating range and differential. The differential pressure switch families offered by Kele come in a variety of housings from standard to water tight NEMA 4X. The pressure differential switch is used to determine air rarefaction or air (non-aggressive gases) pressure drop. Air Differential Pressure Switch Adjustable Micro- Pressure Air Switch T3J6 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. The sample connections located on the side accept 6.35mm (0.25”) OD tubing. JavaScript seems to be disabled in your browser. Senses air or compatible with fluids; Gage, vacuum, differential. There are various optional pressure ranges, and 2 … Differential pressure switch brands offered by Kele can be fixed or field adjustable.

Square D by Schneider Electric 9013FYG2J24 Air-Pump Pressure Switch, Nema 1, 40-60 Psi Pressure Setting, 20-65 Psi Cut-Out, 15-30 Psi Adjustable Differential 5.0 out of 5 stars 8 $27.99 $ 27 . Often used with ovens, dryers, and HVAC systems, these switches detect small differences in pressure. 1-888-863-7389console.log("phone: 1-888-863-7389"); Our price is lower than the manufacturer's "minimum advertised price." Pressure Switches Ashcroft®pressure switches are provided in a variety of configurations to meet most installation requirements in nearly every industry. Conventional applications include : + Monitoring Filters blocked Alarm Device + Monitoring air blower running status. The switch can turn on your compressor when tank air pressure levels drop and more air is needed. 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. A wide variety of switches and circuit styles enables control functions needed for any system. Please note the following model number designations: Y = unloader included, Click To Contact Us Today Or Call: DPS or Differential pressure switches is a device used to actuate an electric switch based on differential pressure across two points and this electric switch used to sense airflow status across the fans, dirty status across the filters in air handling unit or it can be used to connect any control circuit to perform the required operation when switching condition goes on and off. The most common 69J switches can be ordered online with various options. As a result, we cannot show you the price in catalog or the product page. The differential that is actually available to use varies with the pressure range you’re actually working in. They are suitable for air and other non-flammable and non-aggressive gases. By accepting cookies you can optimize your browsing experience. Designed for use in the HVAC industry. 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. Differential pressure switches are a particular type of pressure switch that convert a change in the pressure between two systems into an electrical function. Switches are single pole, double throw (SPDT), so they switch one circuit on or off. As the filter clogs or blocks up, the pressure on the high side will rise and once at the activation point, the pressure switch will change state. Sensors for air and non-combustible compatible gases have an electrical contact output at a specific difference between two pressures. 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. An air switch senses positive, negative or differential air pressure and actuates an internal switch. When the differential pressure exceeds your setpoint, the switch is activated. Series 1831 Manual Reset, No Power Required DPDT Low Differential Pressure Switches which applies to HVAC and high duct static cutout applications. Differential pressure switch for air (DPS) dps-ge51colres.jpg. Often used to indicate clogged filters, they are designed to automate controls or activate an alarm in your process. The air compressor pressure switch will also help your machinery maintain the proper pressure level as you go about your work. They are suitable for air and other non-flammable and non-aggressive gases. Kind of pressure: overpressure, relative : Pressure connection: As pressure increases, available differential increases as well. When the differential pressure exceeds your setpoint, the switch is activated. They can be wired normally open (NO) or normally closed (NC). It may be used to … Filter monitor or flow switch for air, non-combustible, non aggressive gases in air conditioning and ventilating installations. A Differential pressure switch is a device which utilizes a differential air pressure to actuate an electric switch at a pre-set actuation point. The two systems are constantly monitored, and their relative pressure is measured. Operating pressure: 500 mbar Operating pressure: 500 mbar Approvals: EN 1854 HVAC Differential Pressure Switch which applies to controlling air and fire-protection dampers and monitoring air filters and ventilators. 1-888-863-7389. Switches are single pole, double throw (SPDT), so they switch one circuit on or off.
