Vacuum Pump Filters

Vacuum Pump Protection Filters

Essential to protecting the suction side of vacuum pumps from harmful contaminants, the New Alpha Series of Vacuum Pump Protection filters excel in both rough and high Vacuum applications and cover all of the most popular sizes of vacuum pumps. With exceptional results in liquid prevention, the New Alpha elements are constructed using custom engineered oleophobic borosilicate filter media and a unique anti-re-entrainment layer to guarantee exceptional dirt holding and drainage capabilities; preventing damage to rotating parts, the vacuum pump, and process application. Designed with flow-optimisation in mind, the New Alpha Series of Compressed Air and Vacuum filters feature an all new advanced filter head and element design for improved air flow and performance - increasing the energy efficiency within your Compressed Air system. New Alpha Vacuum Pump Protection filters are offered in a range of 16 models with connection sizes from 3/8” to 3” Rp (BSP Parallel), Rc (BSP Taper) and NPT. With a maximum operating temperature of 120˚C (248˚F) and flow capacities up to 288 SCFM (490 Nm³/hr).

Vacuum Pump Exhaust Filters

New Alpha Simplex and Duplex Vacuum Pump Exhaust filters are designed to remove oil mist from lubricated Vacuum Pumps – providing unrivalled filtration performance, reduced exhaust noise levels and an oil free working environment. With exceptional results in oil mist removal from vacuum pumps without internal oil separators, the New Alpha elements guarantee exceptional dirt holding and drainage capabilities with minimal pressure drop, optimising filtration efficiencies to ensure damage prevention and avoidance of costly downtime. Designed with flow-optimisation in mind, the New Alpha Series of Compressed Air and Vacuum filters feature an all new advanced filter head and element design for improved air flow and performance - increasing the energy efficiency within your Compressed Air system. New Alpha Vacuum Pump Exhaust filters are offered in a wide range of connection sizes from 3/8” to 3” Rp (BSP Parallel), Rc (BSP Taper) and NPT, featuring a maximum operating temperature of up to 120˚C (248˚F) and flow capacities up to 288 SCFM (490 Nm³/hr).

Medical Vacuum Filters

Specifically designed to remove liquid, solid and bacterial contamination, the New Alpha Series of Medical Vacuum filters (also known as bacterial filters) are essential for preventing damage to the vacuum pump and reducing the risk of delivering infectious material to vulnerable patients, service engineers and hospital staff. Featuring an easily removable sterilisable vacuum drain flask, a unique push fit element and differential pressure monitor, New Alpha Medical Vacuum filters fully comply with global medical gas pipeline systems standards  ISO7396-1, HTM 02-01, NFPA99 and AS2896, providing peace of mind that potentially hazardous biological contagions will not be exhausted into the surrounding environment. The New Alpha high efficiency medical grade filter element utilises low pressure loss borosilicate glass microfiber media and an open cell reticulated foam pre-filtration layer to capture particulates, bacteria and liquid aerosols whilst maintaining a low differential pressure and improving energy efficiency to deliver low total life costs. Leading the way, our high efficiency Medical Vacuum filters are used on the suction side of a vacuum pump in hospitals, operating theatres, intensive care units, laboratories, veterinary hospitals, dental surgeries and medical vacuum plant installations Worldwide. The safety of our products is paramount; with a guaranteed filtration performance greater than 99.995% (when independently tested in accordance with BS 3928-1969: Method for Sodium Flame Test from Air filters), and meeting the requirements of HTM 02-01, patients and customers have put their complete trust in our product for over 30 years.

Odasorb Exhaust Filters

For rotary vane type vacuum pumps with internal oil separation, oily odours are often a problem especially in confined areas. The Odasorb model OS filter is designed for this application.

This filter element with internal threaded connection and high performance activated carbon filter media can be fitted directly to the pump outlet to provide a safe working environment.

Alternative Vacuum/Compressor Separators

To complement the vacuum filter range, Walker Filtration produce a comprehensive range of alternative air/oil separators and vacuum separators for use in leading manufacturer’s vacuum pump equipment.The construction of each separator consists of a high dirt loading glass microfiber medium supported with steel metalwork and nylon/metal end caps to offer low pressure loss performance.
