When the water level is beyond upper limit, drainage is necessary, otherwise that will cause poor dehumidification.Please be careful to use a wrench to tighten the fitting.The first installation may have an excretion reaction(Not leakage, for the first time the internal pressure is different from the outside, it is necessary to discharge the excess air first). In this case, please wait for a while.Add to CartAdd to CartAdd to CartAdd to CartAdd to CartAdd to CartCustomer Reviews3.8 out of 5 stars4974.4 out of 5 stars1,8224.4 out of 5 stars1,8344.2 out of 5 stars1194.4 out of 5 stars2274.0 out of 5 stars127Price$31.99$31.99$32.99$32.99$38.99$38.99$35.99$35.99$39.99$39.99$57.99$57.99SeriesSFCAWACOFOFROFCPort Size (NPT)1/4" / 3/8" / 1/2"1/4" / 3/8" / 1/2"1/4" / 3/8" / 1/2"1/4" / 3/8" / 1/2"1/4" / 3/8" / 1/2"1/4" / 3/8" / 1/2"Temperature Range41-140 °F41-140 °F41-140 °F41-140 °F41-140 °F41-140 °FMax Inlet Pressure145 psi145 psi145 psi145 psi145 psi230 psiRegulator Pressure Range0-145 psi0-145 psi0-145 psi0-145 psi0-145 psi0-180 psiFilter Rating5 Micron5 Micron5 Micron5 Micron5 Micron5 MicronDrainSemi-AutoSemi-AutoSemi-AutoManualManualManualBowl MaterialPolycarbonate w/ guardPolycarbonate w/ guardPolycarbonate w/ guardPolycarbonate w/ guardPolycarbonate w/ guardPolycarbonate w/ guardNANPU - Dedicate to F.
