LFS
Chemically resistant fan
Radial low-pressure fan with direct drive. LFS fans are used in areas requiring precise air dosing and good resistance to various types of chemicals.
Application
LFS fans are used in:
- in areas requiring precise air dosing,
- in areas requiring good resistance to various types of chemicals,
- in chemical cabinets or rooms located in chemical laboratories,
- in fume cupboards, chemical laboratories,
- when processing plastic, shrink wrapping.
