Vacuum-To-Go Desiccator Vacuum Pumping System

EMS introduces the solution for a compact vacuum solution for all small laboratory equipment

A diaphragm oil-free pump that may be used on glass, stainless, as well as plastic desiccators. With a hydrophobic PTFE in-line filter membrane in place, particles larger than 0.1 micron are contained. With 1/8 HP, maximum pressure of 50 PSI and a maximum temperature of 38°C, the pump prevents fluid and air contamination, as well as exhaust back- up. The pump features an oilless operation, rugged construction, easy hose connections, and 50 PSIG maximum continuous pressure.

Features

• Prevents all fluid and air contamination of vacuum pumps
• May be used to prevent hazardous exhaust back up
• Oilless Operation
• Rugged Construction/Low Maintenance
• 50 PSIG Maximum Continuous Pressure

Vacuum 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

EMF 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.

EMF3

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

EMF 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

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

Ordering Information

Fomblin® Vacuum Grease, AR555 Grade

Fomblin AR555 is a homogenous white grease with excellent rust inhibiting and solvent washout resistance properties. It is suitable for lubricating mechanical parts requiring boundary (extreme pressure) lubricating properties, and suitable for use in several operating conditions, high load, high speed, and where a wide temperature range is requred.

The operating temperature range is from -20°C to 250°C. Its properties make it suitable in "lubricating for life" applications. This vacuum grease is an excellent lubricant for sliding elastomer seals, and exhibits the chemical inertness typical of the Fomblin range.

It has a very low vapor pressure, <10^-7 mbar at 20°C, and is suitable for use in the presence of gaseous and liquid oxygen under severe condition.

• Very wide temperature range -20°C to 250°C
• Excellent rust inhibiting properties
• Excellent wear resistance properties
• Excellent resistance to aggresive chemicals

Typical Properties

Foreline 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.

* Available in stainless steel upon special request.

Ultragrade 19 Oil

Edwards Ultragrade 19 Oil is specially recommended for use in clean pumping applications.

The oil offers reduced maintenance cost, longer fluid life, and a cooler running pump.

Available in two sizes.
