General Information

• High efficiency valves move more gas volume
  The heart of any compressor is its valve assembly and Blackmer valves are specifically designed for non-lubricated gas applications. With precisely engineered clearances, spring tension, and a special finish, these valves seat more positively so more gas is moved with each piston stroke. Blackmer valves offer greater strength, quiet operation, and long life.
• O-Ring seals-head and cylinder
  The head and cylinder are sealed with O-rings to ensure positive sealing under all operating conditions.
• Pressure assisted piston rings for positive seating
  Constructed of self-lubricating PTFE, Blackmer's special ring design provides maximum sealing efficiency with minimal friction wear. The result: peak performance and extended compressor service life.
• Heavy-duty crankshaft
  The ductile iron crankshaft is precision ground with integral counterweights for smooth, quiet operation. Rifle drilling ensures positive oil distribution to the wrist pin and connecting rod bearings.
• Pressure lubricated crankcase
  A rotary oil pump provides positive oil distribution to all running gear components for long life and minimal wear.
• Wear-resistant crosshead assemblies
  Designed for maximum lubrication and wear resistance.
• Ductile iron pistons
  Heavy-duty ductile iron pistons are connected with a single positive locking nut which eliminates potential problems associated with more complex designs.
• Self-adjusting piston rod seals
  Crankcase oil contamination and cylinder blow-by is prevented with loaded glass-filled PTFE seals which maintain a constant sealing pressure around the piston rods.
• Ductile iron construction
  All pressure parts are of ductile iron for greater resistance to both thermal and mechanical shock.
