SMC ALF400 to ALF900 Auto-Feed Lubricator (Rc1/4 to Rc2)

SMC ALF400 to ALF900 Auto-Feed Lubricator (Rc1/4 to Rc2)

Key features

  • Oil pressure-fed from an ALT-5/-9 tank through a felt-filtered nozzle; a float and lever valve stop feeding when the bowl is full
  • Eliminates oil shortage problems and refilling labour; usable differential pressure (tank minus line) 0.1 to 0.6 MPa
  • Six body sizes ALF400 to ALF900 with polycarbonate bowl and bowl guard
  • Accessories/suffixes not listed: B bracket (ALF400 to 600), X208 metal bowl with level gauge, R right-to-left flow
  • Thread Rc standard; NPT (N) and G (F) available. CE/UKCA
