Machine foot HLF series

equipmentfor food industry machineryNBR

Overview

Hygienic levelling feet designed for demanding sanitary environments such as food processing, pharmaceuticals and biotechnology. The EHLF series integrates a floor lock plate for secure anchoring and a protected spindle to prevent ingress of contaminants, providing easy cleaning and traceability of critical components.

Key benefits

• Secure anchoring: floor lock plate fixes equipment to the floor to minimise movement and vibration.
• Contamination prevention: protected spindle and sleeve reduce dust, dirt and moisture ingress.
• Hygienic geometry: rounded, smooth surfaces enable efficient cleaning and compliance with sanitary design principles.
• Vibration and slip reduction: vulcanized NBR rubber base provides anti-slip and damping properties; rubber part supplied with FDA CFR 21 177.2600 certification and unique batch ID for traceability.
• Corrosion resistance: stainless steel construction suitable for harsh cleaning regimens and prolonged service life.

Materials

• Base plate: stainless steel AISI 304 or AISI 316.
• Spindle: stainless steel A2-70 or A4-70.
• Rubber base: NBR (nitrile rubber, CAS no. 9005-98-5), vulcanized rubber part with FDA certification (FDA CFR 21 177.2600) and batch ID for traceability.
• All materials selected for high resistance to chemicals, common cleaning agents, oils and fats.
