LAB4DC-B
LAB4-DC Automatic Dehydrator, 48-60 VDC

The LAB4 Automatic Pressurization Dehydrator is designed for reliable pressurization of elliptical waveguide, coaxial cable and rigid transmission line systems. The dehydrator includes a self contained completely automated air drying system that utilizes a pressure swing moisture absorption cycle to provide pressurized dry air. This eliminates the need for replacement or manual reactivation of the desiccant and makes the LAB4 dehydrators ideal for unattended operation at even remote sites.The pressure output is adjustabled in the field to operate anywhere between 1 kPa and 6 kPa (0.15 psig and 0.87 psig).A factory set safety valve at 7 kPa (1 psig) protects the products of destruction by over pressure.
