The DS1 Mechanical Drain is a pneumatically designed drain that automatically removes liquid, oil, and water contaminates from compressed air system components. The design, which includes an efficient bowl size with a large quiet zone allows for no re-entrainment of liquid back into the air system. The metal bowl is also compatible with all compressor lubricants.

The Evacuator™ is the most reliable demand drain solution for large condensate loads in a compressed air system. The Evacuator™ is available in a 52 oz. pneumatically operated version or a 27 oz. or 77 oz. electronically managed system version. The electronically managed system incorporates microprocessor based electronics for self-diagnostics, error correction and host computer communications capabilities.

The NA750 is the ultimate high pressure demand operated drain. The unit is fully automatic - no electricity is required. Its low profile gives you the advantages of installing it in areas where the vessel to be drained is only a few inches from the ground. A unique air valve design uses a magnetic force to ensure both a positive opening and closing that will prevent air loss. The magnetic force is positioned away from the condensation level to prevent any attraction of metal particulate. An innovative ball valve support and positioning system prevents the side loading problem which otherwise would cause premature sealing failure around the valve stem. The 1/2" ball valve ensures that scale and rust will exit the vessel. The NA750 will not clog which eliminates the need for a strainer.

Automatic Pneumatically-Operated Condensate Drain

Gardner Denver pneumatically operated condensate drains are designed to ensure that manufacturing processes and products do not become contaminated by ensuring that liquid oil and water condensates are discharged from the compressed air stream. The SMD/TMD/BMD Series features a no air-loss actuated design which operates on demand. The discharge port closes before any compressed air is lost. Air powered pistons are used for positive opening and closing of discharge port.

Condensate enters the drain through one of the two inlet connections. As condensate is collected and the translucent reservoir fills, a stainless steel float mechanism rises. When the condensate reaches a designated level, the float mechanism actuates an isolated magnetic trigger assembly. The trigger assembly directs control air to the valve actuator, which in turn opens a full-port drain valve.

Condensate will then exit the unit. As the float drops, the trigger assembly closes the control air line and the valve actuator closes the ball valve. The drain is then returned to the collection mode.
