Series GC gas coalescers is a unique two-stage filtering concept for use on air and gas streams requiring both solids and liquids removal. By combining the principals of impingement baffling with the most efficient filtration and coalescing cartridge designs, the GC series will remove virtually all entrained water and hydrocarbons in free, fog or mist form. Any solids larger than one micrometer will be removed from the stream at the same time. The flow enters the inlet where the impingement baffle removes solids and some entrained liquids, they collect in the quiescent sump. Mist and minute solids flow up to the coalescer cartridges where the oil and water are coalesced and the solids removed. The flow through the coalescer cartridge is inside to outside. Solids remain in the coalescer cartridges and coalesced water and oil fall by gravity to the cartridge mounting plate. The stream then flows through the centre pipe to the outlet of the vessel. Result: a clean and dry gas!
