How does Airtow Trailers’ air suspension work?

Air is pumped directly into the air bags by two independent air compressors, one on each side of the trailer.  The axles on each side of the trailer are monitored by electronic sensors. As the axle deflects because weight is added, the compressor in turned on to increase the air bag pressure. When weight is removed the sensor initiates air release from the air bags. This allows a super smooth ride when the trailer is empty and a super smooth, firm ride when fully loaded.
