Product feature


Oil-injected screw compressor

Advantages: The pressure is stable, and it can be post-installed to remove water, dust and bacteria;
Disadvantages: Exhaust gas contains a lot of oil, causing pollution to the cloth, which does not meet the production requirements of melt-blown cloth.

Roots screw blower

Advantages: The exhaust does not contain oil or water
Disadvantages: The exhaust temperature is too low, contrary to the temperature requirements of the mold spinneret, which originally required heating and constant temperature, but he sent cooling air, which is likely to cause unstable melting temperature. The spinneret contains crystals, dust, and Bacteria, the pressure is unstable, because of its characteristic is that there is no pressure ratio, the outlet pressure is 80kpa, if you want to add sterilization and pre-dust removal, it will cause insufficient pressure, and the spinner does not form or block.

Oil-free screw blower

Advantages: stable pressure (40kpa ~ 150kpa variable frequency adjustable), high exhaust temperature (outlet 120 degrees Celsius), helps to constant melting temperature, can be oil-free, water-free, dust-free, sterile
Disadvantages: the price is more expensive.
