A portable controller unit for delivering pressurized air to a compression device does not require the use of tubing to make internal or external connections. The controller unit includes a molded, one-piece manifold base on which an air compressor and a valve mechanism are mounted. The manifold base includes a plenum formed inside the base during molding of the base and a connector component formed during molding of the base for releasably securing the base to the compression device. The plenum fluidly connects the air compressor to the valve mechanism. The plenum extends through the connector component and fluidly connects the connector to the valve mechanism so that when the base is secured to the compression device, air can be delivered from the air compressor through the connector component to the compression device.
