Duct Static Pressure Switch

An air switch senses positive negative or differential air pressure and actuates an internal switch.

Duct static pressure switch.

An optional discharge air static high limit reduces the fan speed if discharge static pressure increases above its setpoint. With over 1 8 million parts in stock kele makes it easy to avoid project delays. Kele is the leading supplier of building automation products. Switch contacts are spdt with solder type connections.

Ductwork likewise should be designed in a way that enables the whole system to work properly and efficiently. On a call for full pressure the fan runs at full speed. Pl liquid pressure sensors switches monitor flow and prove pumps chillers and valves. Rely on grainger for a wide range of duct pressure switch options.

Rely on grainger for a wide range of duct pressure switch options. Hvac systems regardless of size are designed to move a certain amount of air. The dwyer model 1900 5 mr manual reset pressure switch is designed to monitor duct static and shut down the blower when excess pressure occurs. Duct static control specifications are taken directly from vendors standard specifications.

Order the a 399 duct pressure kit separately. Duct pressure switches automatically start and stop auxiliary devices like electronic air cleaners duct heaters humidifiers exhaust fans and duct booster fans. Duct pressure switches automatically start and stop auxiliary devices like electronic air cleaners duct heaters humidifiers exhaust fans and duct booster fans. An air switch senses positive negative or differential air pressure and actuates an internal switch.

As duct static pressure increases the supply fan speed reduces. These sensors can be used to measure static pressure in a large range of liquids and gases. Static pressure is a drag literally. Kele carries duct static pressure sensors and pressure accessories to fit your specifications.

To maintain the static pressure set point the supply fan will modulate appropriately but the set point is usually determined based on design conditions before the building is ever built. Belimo offers a broad range of air duct sensors covering all standard measurement values. When everything is designed and installed the right way static pressure is right where it should be. Air dp sensors switches air dp switches for fan proving single or multi range air dp sensors for dirty filter monitoring and air flow or pressure control.

The controller uses a static pressure sensor located in the supply duct at the end of the longest run to modulate the supply fan to control duct static pressure. The switch must be manually reset before the system can start again.
