Hi-line, compressed air filter units
Compressed air filtration units offer high efficiency, low cost & universal fixings
News Release from:
Hi-Line Industries Ltd
A new range of compressed air filter units from Hi-line have been designed with economy and efficiency in mind, for the removal of oil, water, particulates and gaseous aerosols from compressed air systems using a range of high performance filtration elements.
The die-cast filter housings are produced from high-grade aluminium with a special feature of both external and internal surfaces being Alu-Chrome treated. In addition, 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 patented pleated filter media which combines maximum efficiency with long service life and very low differential pressure drop. They are available in several grades to accommodate particle removal down to 5 micron or 3 microns in size, with oil removal at 0.5 micron or 0.01 micron levels. These elements provide impressive filtration efficiencies from 99.99% to 99.99999% 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 7 bar pressure and 20°C, while all elements are validated and ensure the highest quality of compressed air to ISO 8573.1 standard.
To comply with requests from their distributors and agents, Hi-line has used standard connection technology between their filter elements and housings. This ensures maximum versatility and choice for end users, who would not therefore be locked-in to any supplier for consumable spares, guaranteeing maximum ease of use and optimum inter-changeability. The threaded aluminium housings are available with port connection sizes from ½” to 4” BSP, offering flow rates from 42 to 3672Nm/h.
Filter housings with 1/2“ BSP ports, supplied with any grade of filtration element can be supplied at less than £50 and ex-stock delivery, showing immediate savings over equivalent competitor products.
