This is suitable for use in approximately 96 – 98% ultimate vacuum. This has been used for distillation, drying, extraction and filtration in chemical and many other industries. This is designed based on the technology of reciprocating compressor and has an excellent performance. Oil-free type (PHNL Series) is also available with many experiences.

This is most suitable for use in higher ultimate vacuum and realized 99.07 – 99.6% for single stage and 99.98 – 99.99% ultimate vacuum for two stage. Extremely low oil consumption contributes to the reduction of environmental load. In addition, a liner is placed on the sliding surface for slide valve on the cylinder and this pump had increased durability by precise machining and assembling.
