The DS1 Mechanical Drain is designed to automatically remove liquid, oil, and water contaminates from compressed air system components. Liquid contaminates collected in the bowl cause the float mechanism to rise. When the liquid reaches a specific level, the float actuates the pilot drain orifice which allows line pressure to open the valve and evacuate the liquid/particulate contaminates. As the liquid level falls, the float closes the pilot drain orifice prior to any significant air loss from the system. A manual override is provided as an option which allows for drainage of the system on demand. To drain, simply push up on the attachment. Pull attachment back down when draining is complete. The manual override only adds 1.3
DS2 Evacuator™ Drain
The DS2 Evacuator Drain Valve is a state-of-the-art, automatic solution for compressed air condensate removal. Since power costs are by far the single largest expense in operating air compressors, cost-conscious consumers frequently install the Evacuator. Not only does the Evacuator’s rugged design effectively prevent moisture damage to dryers, air tools, gauges and other critical components, it wastes no compress ed air —as do many competitive Mod els! This is critical to an air system, as a single drain allowing compressed air to escape can easily cost $1,500* a year in hidden expenses. The demandoperated Evacuator eliminates the need to constantly make adjustments as ambient conditions change. If you are looking for maintenance-free draining that wastes no compressed air, the DS2 Evacuator is the answer! *Based on 1/2
DS3 Electric Timed Drain
Gardner Denver has developed two electrical timed drains: the mini and the general. The mini is ideal for smaller filters. The general is better suited for larger filters, refrigerated dryers, receiver tanks, and other general purpose applications. Both drain valves feature state of the art electronic timers and brass valve bodies, which come standard. The general model is also available in corrosion free stainless steel and high pressure.
DS4 Motorized Ball Valve Drain
When pipe scale contaminants from deliquescent dryers or other large particles present in your condensate keep plugging or holding open your common drain valve, it’s time for the DS4 motorized ball drain valve from Gardner Denver. This valve is designed to handle all types of contaminants without clogging or sticking open. It consists of a 1/2
Why Use Drain Valves
One of the most problematic contaminates in your compressed air system is the condensate from your compressors, aftercoolers, receivers, filters, and dryers. Condensate consists of compressor oil, condensed water, dirt, and other contaminants that are being introduced into the inlet of the compressor. Condensate, if not properly removed from the system, can be detrimental to your process and results in downtime and equipment failure. This is why Gardner Denver has developed a comprehensive line of condensate drain valves to suit all your system needs. The following chart shows suggested uses for each type of valve.
