Seeclutch and brake air volume/ratedata pages 365 and 366.Example: Nexen Brake Model T-1000Average Volume = Vn + Vo/2 = 1.739+ 8.656/2 = 6.067 cubic inches.B.Multiply the result in step A by themaximum cycle rate per minute.Example: At 20 cycles per minute;Cubic Inches per Minute = 20 x6.067 = 121.34C.Determine the CF factor for the air pressure setting from the graph on page 366.Example: The CF factor for 80 psi = 6.5D.Multiply the result in Step B by the CF factor to determine the cubic inches of free air;Example: 6.5 x 121.34 = 788.7 cubic inches per minute of free air.E. Divide the result in step D by 1728 to convert to cubic feet per minute.Example: 788.7/1728 = 788.7/1728 = .456 cubic feet per minute.NOTE: Nexen recommends one drop of oil for every 20 cubic feet of air.F. To determine the amount of time between drops, divide 20 by the flow rate.Example: Divide 20 by the result of step E; 20/.456 = 44 minutes between drops of oil.WARNING3 ⁄ 437⁄ 641(14.68 mm)19⁄ 32(40.48 mm)1 7⁄ 64(28.19 mm)12(69.85 mm)3 7 ⁄ 8(98.43 mm)PRESSURE DROP (PSIG)755025005 5 ⁄ 16(134.94 mm)1 5 ⁄ 16(33.34 mm)AIR FLOW-(SCFM)SLOTS ACCEPT #8 OR 4 mmMOUNTING SCREWS19⁄ 32(40.48 mm)5 10 15 20 25 30 35 40 45 501 11 ⁄ 16(42.86 mm)3 5 ⁄ 8(92.08 mm)1 19 ⁄ 32(40.48 mm)1 19 ⁄ 32(40.48 mm)The polycarbonate plastic material used to manufacture the sight dome may be attacked by certain chemicals. Do notuse this lubricator on systems with air supplied by a compressor lubricated with synthetic oils or oils containingphosphate esters or chlorinated hydrocarbons. These oils can carry over into the air lines and chemically attack andpossibly rupture the sight dome. Also, do not expose the sight dome to materials such as carbon tetrachloride,trichlorethylene, acetone, paint thinner, cleaning fluids, or other harmful materials, for they too will cause the plasticto craze and/or rupture. For use in environments where these, or any, chemicals may be present, consult the factoryfor approval.343
