Description
Especially suitable for the pumping work for cold- producing maintenance (for the vacuum pumping with R22or R134a,R404A,R407 as cold-producing medium)medical appliances printing machinery vacuum packing gas-analysis and hot -forming plastics. And they can also be used as the fore-stroke pumps of all kinds of high-vacuum equipments.
Features
■ Preventing oil-returning design
The passage for gas entering is specially designed which can prevent the oil flowing back and so prevent the pumped container and tubes from being polluted.
■ Environment-protecting design
The tank is separated and there are separate in a devices at the exhaust port, It can avoid oil-spraying and reduce pollution.
■ Alloy aluminum casing
Alloy aluminum casing is used in this kind of electrical machinery, it has high heat-scattering efficiency which can keep the pump running normally long-lasting and it has better outer-figure quality.
■ Overall design
The electric machinery and the pump are wholly designed and direct drive which makes the product more compact, lighter and more rational.
■ Forced-feed lubrication system(dual-stage vacuum pump)
The products incorporate the lubrication system designed to provide clean, filtered oil to all internal bearings and wear surface regardless of the pump operating pressure. Cleaner it means reduced maintenance and lower operating costs.
■ Dual voltage (115/230 V) and Frequency Range (50/60Hz)
■ Achievable rating as low as 20 microns
■ Unit is factory wired for high voltage (230V). Refer to operating manual to switch to low voltage (115V) if required.
