Level 1•••

Free of oil and grease1)

Pure oxygen (O2) is supplied as process gas at approx. 1 mbar
A high-frequency generator forms an electromagnetic field as energy source
e oxygen molecules are ionized and transferred into the highly reactive plasma✔ individual parts free ofoil and grease

Plasma cleaninge process chamber is continuously supplied with oxygen while the used gas(= decomposition product of the hydrocarbons) is removed by the vacuum pump

✔ assembly and adjustment

Venting of the process chamber••

Ventilation of the process chamber with ambient air
e cleaned products are individually packed and sealed in silicone-free PE bags

Not recommended for oxygen applications

SUCO only recommends the use of EPDM sealing for oxygen applications.
e maximum permitted pressure depends on the housing material.
