Hi-Line Unveils Compressed Air Filter Units
A range of compressed air filter units from Hi-line has been designed for the removal of oil, water, particulates and gaseous aerosols from compressed air systems. The die-cast filter housings are produced from high-grade aluminium with external and internal surfaces being alu-chrome treated. They are also subject to a tough epoxy baked-on paint finish in 'compressed air blue' - RAL 5015.
These treatments are designed to provide long-term protection, even when subject to the harshest operation conditions, ensuring a long service lifetime. Optional electronic or pneumatic differential pressure gauges can be fitted as required. The oil/water condensate is removed via a highly efficient robust brass drain assembly with the built-in capability to attach a 6mm dia nylon condensate discharge line.
The filtration elements use pleated filter media that combines maximum efficiency with very low differential pressure drop. They are available in several grades to accommodate particle removal down to five micron or three microns in size, with oil removal at 0.5 micron or 0.01 micron levels.
These elements provide impressive filtration efficiencies from 99.99 per cent to 99.99999 per cent with a further grade being specific to oil/aerosol removal down to 0.003mg/m utilising activated carbon technology. These figures are for operation at seven bar pressure and 20C, while all elements are validated and ensure high quality of compressed air to the ISO 8573.1 standard.
To comply with requests from distributors and agents, Hi-line has used standard connection technology between filter elements and housings. This ensures versatility and choice for end users, who would not therefore be locked-in to any supplier for consumable spares. The threaded aluminium housings are available with port connection sizes from 1/2in to 4in BSP, offering flow rates from 42 to 3672Nm/h.
