F003 Vacuum Pump Inlet Filter

LVGE Ref.: LOA-202ZB

OEM Ref.:F003

Filter Element Dimensions: Ø128*65*125mm

Interface Size: KF40

Nominal Flow: 100~150m³/h

Product Overview:

F003 Vacuum Pump Inlet Filter (Model LA-202ZB) is a core protective component installed at the suction port of vacuum pumps, specially developed for vacuum equipment with a flow rate of 100~150 m³/h. As a high-performance vacuum pump inlet filter, it effectively intercepts inhaled dust and solid particles, isolating contaminants from entering the pump cavity and vacuum pump oil, lowering mechanical abrasion of pump parts, extending pump service life and prolonging maintenance cycles for your vacuum system.

Built with full 304 stainless steel seamless welded housing, this vacuum pump inlet filter delivers outstanding tightness and corrosion resistance, suitable for industrial vacuum, laboratory, packaging, electronics, chemical and other medium-flow vacuum working scenarios. Multiple interchangeable filter elements are optional to match dry, humid, high-temperature and corrosive working environments, realizing one filter for multi-scene use.

Interface Size: KF25/KF40
