Presair, the leading air pressure switch manufacturer, produces a wide variety of pressure switches for monitoring and controlling equipment. Many mounting styles are available either factory set or adjustable to fit multiple application requirements. Our air pressure switches have worldwide approval and have a long life cycle making them ideal for OEM applications.
Factory Set Pressure Switches
Presair’s factory set pressure switches are available small and compact, heavy duty, printed circuit board mount, and have the ability to sense pressure levels as low as 0.25 inches of water. Pressure switches can be factory set from 0.25 inches of water up to 125 psi when using our heavy duty style. Our factory set pressure switches have excellent repeat-ability and are proof tested when high pressure environments may occur.
Adjustable Pressure Switches
Presair’s adjustable pressure switches are available in our heavy duty models with a mounting foot print of 2.5 inches, or we can sense low pressure with an adjustable range of 0.25 inches of water to 35 inches of water. The switches are easily adjusted using a small hex screw that turns clockwise to increase the pressure point or counter-clockwise to decrease.
Pressure Monitoring Device
Presair has recently released a low cost, pressure monitoring device. The pressure monitor provides notification and prevents issues before downtime occurs. Versions tailored to meet the needs of manufactures, the monitor notifies personnel using visual, audio and even text alerts when air pressure rises or falls in a system.
Pressure switches are designed and manufactured to exacting standards to meet the needs of original equipment manufacturers and instrument makers for low cost, stable switches and good repeat accuracy. Presair manufactures pressure switches with accuracy in mind. Our standard pressure switches have a dead band of ±10%, and custom options can be built for a tighter or wider dead band.
Custom options are available such as material, gold contacts, latching switch types and non-standard adjusting ranges. Contact our direct customer service for more information.
