House Air/Vacuum Performance Work Statement

USMA Bartlett Hall Science Center has compressed air and vacuum distributed throughout building. These services emanate from two central facilities. One is in the subbasement; the other is on the roof. Preventive maintenance is required on both systems.

The equipment in the subbasement consists of:

Quadraplex Hitachi model 110U-8.5CG2H air compressors with Weg 15HP motors and two dual-tower dryers (Trident Dryspell with DS 31-200 controllers).

Triplex Busch model RC0400.B033.1037 vacuum pumps with Baldor 15HP motors.

Both have control systems integrated by Amico Air and Vacuum Systems.

The equipment on the roof consists of:

Triplex Powerex OBS150700E air compressors with Baldor motors and a single dual tower dryer.

Duplex Busch model RC0400.B033.1035 vacuum pumps with Baldor 15HP motors.

Both have control systems integrated by Engineered Medical Systems and

Equipment.

The preventive maintenance being sought will be performed quarterly and annually. A service report will be supplied after each maintenance visit
