for the Davenport®

Model BN Revolving Head

U.S. Patent 5,205,376

AIR LUBE SYSTEM (NP-2250-ALS-SA)

• The Air Lube System creates a continuous positive air seal preventing foreign matter from contaminating the "heart of the machine".
• Provides simultaneous lubrication to all five Outer Work Spindles and NP Solid Bronze Bearings.
• Air Lube System creates an air lube oil cushion for the Revolving Head which virtually eliminates metal to metal contact guaranteeing years of unmatched performance.
• The patented system automatically prelubricates the entire machine before start up.
• The system air pressure is preset at approximately 80 P.S.1. and requires 2-4 cubic feet of air/minute.
• The automatic red warning light feature indicates low lube oil levels or loss of air pressure within the system.
• Dimensionally, the Air/Lube Distribution Box is designed to fit into the same location as the Bijur reservoir to allow for easy installation and removal.
• The clear polycarbonate front cover allows for easy visual inspection of oil levels. A single large diameter oil filler spout distributes oil to all three reservoirs to a total capacity of six quarts.
• The 35 micron porous metal filters provide nine times greater filtration capacity to each of the three reservoirs than the previous lubrication system provided to the entire system.
