Description: 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 will open when buoyancy increases, in order to drain condensed liquid. Features: This compressed air condensate automatic drainer is significantly different from traditional mechanical automatic drainer, which is belong to continuous drops drain. Shell is made of casting aluminum alloy, with plastic powder coating surface, resistant to corrosion. 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 new generation and great choice of compressed air equipment drainer. This is a quite stable drainer which has great performance and low failure rate. Specifications: Model: HAD20B Port Size: Inlet=Outlet=1/2BSP Maximum Pressure: 20bar Maximum Temperature: 100℃ Maximum Capacity: 400L/H Weight: 602g(approx.) 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 will 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 cleaned each year.When cleaning, you can use soap water or dish-washing liquid to clean, do not use solvents, so as not to damage the rubber fittings. Package Includes: 1 x Drain Valve 1 x Pipe Fitting Note: Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
