Exhaust Filtersarrow12Vacuum Pump Exhaust Filters

Vacuum Pump Exhaust Filters for Vacuum Rotary Vane Pumps remove all visible oil mist and smoke from vacuum pump exhaust, even when it is saturated with oil. The high efficiency filter cartridge continuously drains the collected liquid, allowing the user to recover expensive lubricating fluid. Filters are for pumps with flow ratings ranging of 3 cfm and non-hazardous/non-corrosive applications. Port size is ½" NPT.

Features

  • Eliminate 99% oil mist and smoke from vacuum pump exhaust
  • Prevent oil accumulation in ductwork
  • Recover expensive lubricating oils, and automatically return filtered oil to pump
  • Eliminate potential OSHA and EPA violations
  • The filter assemblies are shipped with filter cartridges, pressure gage (20 cfm and larger), and final filter pad.

Specifications

  • Maximum Flow Rate: 3 CFM
  • Material: Nylon
  • Maximum Seals: None
  • Maximum Temperature: 250°F (121°C)
  • Shipping Pressure: 15PSIG
  • Dimensions: 2" Dia. x 3.7" H
  • Weight: .25lbs (0.1kg)
  • Port Size: ½" NPT

Downloadable PDFOil Mist Filterarrow12EMF Oil Mist Filters

We are pleased to offer not only the vacuum pumps but also the oil mist filters to help you deal with exhaust mist from the pump which sticks to any surface that it touches and becomes a dust magnet.

Mist filters capture oil mist from the outlet of pumps, which would otherwise be ejected into the atmosphere. This may happen when you use gas ballast or when you pump high gas throughputs. You can also return oil trapped in the mist filter back to the pump, although you must ensure that the process gases will not contaminate the pump or pump oil.

For the E2M1.5 use the EMF3. For the RV3, RV5, and RV8 use the EMF 10.

arrow12EMF3

Features

  • Protection from oil mist emissions as required by COSHH and health and safety regulations
  • Use of optional oil return kits results in reduced oil level maintenance and savings in pump oil
  • If the oil element becomes blocked, an integral pressure relief valve opens
arrow12EMF 10

The EMF10 mist filter is suitable for use with RV3, RV5 and RV8 pumps. They are very efficient at 99.999% DOP test and are also azide proof. The white bottom half of the body is semi-transparent, allowing the oil level to be monitored. The EMF filters have a unique odor element which neutralizes the smell of oil mist.

Supplied with NW25 clamp, centering ring and 'O' ring, NW25 to ¾ inch BSP adaptor

foreline traparrow12Foreline Traps

These rechargeable in-line traps effectively block oil backstreaming from mechanical pumps. Any mechanically pumped system, even one with a turbo pump, should have a foreline traps. The trap is placed in the foreline between the roughing pump and the diffusion or turbo pump. It uses a disposable, oxygen-free copper maze absorbent which requires no liquid nitrogen and will not hold water. Typically the maze is replaced every 1-2 years. The seamless body is available in aluminum.

  • A quick change clamp for replacement of maze
  • A viton “O" ring end cap
  • A recessed screen
  • Available in five pipe diameters

Replacement elements (Copper Maze) also available.

Vacuum Monitorarrow12Vacuum Monitor

This vacuum monitor allows you to monitor the vacuum level in the foreline between the roughing pump and the diffusion (or turbo) pump. A high value would indicate a leak in the system or possibly an inefficient roughing pump. Comprised of a thermocouple gauge control module and cable. The unit can mount directly to the Foreline Trap via a thermocouple (TC) port supplied at no charge when ordered with a Foreline Trap. The 3-station version of the Vacuum Monitor allows the vacuum levels of several pumps to be measured.
