PSW-280 Aquatec Pressure Switch 80 psi shut off 1/4 tubing TSO [PSW-280]

$22.00

PSW-280 Aquatec Pressure Switch 80 psi shut off 1/4 tubing TSO

Aquatec Pressure Switch + Quick Connect Electrical Wire Plugs (made in USA)

Brand: Aquatec  (Genuine Aquatec components)

Model: PSW-280       (80 psi cut off, 1/4" inlet/outlet)

This pressure switch is used to control the on/off of the Aquatec booster pump 6800 series and 8800 series.  Typical application is installed on a RO reverse osmosis water system.  Instruction is included inside package.

This pressure switch comes with quick connect wire plugs that connect quickly to Aquatec booster pump and Aquatec transformer.

This switch has 1/4" inlet and outlet quick connect fitting.  All you need to do is to push in a 1/4" OD tubing into the inlet and outlet all the way in, the fitting will seal itself.  To remove the tubing, you just need to push the plastic ring firmly against the fitting then you can pull out the tubing.

Pressure Setting:  It is pre-set at 80 psi cut-off pressure, but it is also adjustable.  The adjustable range is 70 to 110 psi

Operation:  When the pressure switch is connected to a Aquatec pump and Aquatec transformer, it will turn on the pump when pressure switch is sensing below 80 psi; then it will turn off the pump when the pressure is sensing 80 psi or above.


We also carry many other variation of the Aquatec pressure switches.
