Vacuum Hydro Aspirator Filter Pump - Humboldt-

Vacuum Hydro Aspirator Filter Pump - Humboldt- - Avogadro's Lab Supply


SKU: H-12090

The hydroaspirator will perform under both high and low water pressure conditions. The pump features a ball-type positive action valve in the suction tube which will prevent water backflow if the pressure is reduced.
The water inlet connection thread is a standard 3/8" NPT taper.The hydro aspirator vacuum filter pump is manufactured in the U.S.A. by Humboldt.

Vacuum Inlet: 9 mm / .35"
Water Outlet: 9 mm / .35"
Length: 76 mm / 3.0"
Vacuum generated @ 30 psi 29.5" Hg

At a water pressure of 30 psi this aspirator will reduce atmospheric pressure by 29.5" Hg.

Standard pressure 29.92" Hg = 1 atm
Vacuum - 29.50" Hg
Net pressure = 0.42" Hg = 0.014 atm

The actual vacuum attained with this pump is directly proportional to the water pressure and current barometric pressure!
