This compressed air condensate automatic drainer is a mechanical automatic drainer which has casting aluminum alloy shell and inside float ball drainage system.Drainer outlet is closed when drainage buoyancy is smaller than floating ball weight plus compressed air pressure; and it open when buoyancy increases, in order to drain condensed liquid. This compressed air condensate automatic drainer is significantly different from traditional mechanical automatic drainer, which is belong to continuous drops drain. Metal powder coating , to . Automatic drainer is extremely reliable in operation, no electricity needed, no noise, no loss of compressed air. Drainer has big drainage outlet that is not easily blocked; it is a and great choice of compressed air equipment drainer. Temperature of Media:Normal Temperature Media:Water Power:Pneumatic Model Number:Float Drain Pressure:Medium Pressure Structure:Control Actuator Mode:Without Manual And Instruction Thread Type: This is a quite stable drainer which has great performance and low failure rate. Model: HAD20B Port Size: Inlet=Outlet=1/2BSP Max. Pressure: 20bar Max. Temperature: 100 Celsius Max. Capacity: 400L/H Weight: 602g(.) Instruction: Before installing this drainer, please use compressed air to remove impurities in the piping till it is completely clean. Install this automatic drainer beneath the drainage device of equipment, otherwise condensate be filled and affect drainage. Maintenance Inspect the drainer once a week. Operation method: open manual drainer valve to drain water till compressed air in equipment enter the drainer, after a few seconds then closed valve.If drained water is more than 0.5 liters, there is a blockage and drainer need to be cleaned completely. Internal parts should be taken out and cleanedeach year.When cle, you can use soap water or dish-washing
