1.6 Oil Filling on Gear Box
After level installation and correct rotation has been established, fill the pump with the recommended
gear oil through the oil fill port if it is not shipped without oil. Oil level should be at the 3/4 position on the
oil sight glass, as shown:
We recommend using Airtech Part Number ATO-3000-01, which is supplied by Airtech.
The following table gives the approximate quantities of oil required for each model.
Pump Model Capacity (liter)
VCX 60 0.60
VCX 155 / VCX205 0.5
VCX 100 / VCX100B / VCX 150 / VCX150B 0.75
VCX 250 / VCX250B / VCX 300 / VCX300B 1.10
VCX 255 / VCX 305 0.90
VCX 400/ VCX 505 1.10
VCX 515 1.80
Do not add fill oil with pump running! Do not overfill.
Caution: Running the compressor before adding oil to the gearbox could result in severe damage
to the unit. Use of oil that does not meet the recommended specification could result in damage to
the unit and void the warranty.
1.7 Lubrication of the bearings (VCX 400/505 ONLY)
The bearings on the drive side of the pump must be lubricated by gear oil using a splash lubrication
principle. The bearings on the non-drive side need to be greased every 5,000 operating hours (see
Section 4.3 for the maintenance schedule). Airtech supplies grease specifically for this purpose: Airtech
Part Number ATG 5400.
