What’s a small compressor?

Compact compressors are small devices that supply compressed air for low pressure tasks such as inflating balloons or tires. They are easy to store and carry, with motor sizes ranging from 1/8 to 2 horsepower. Some models have a small tank, while others supply compressed air directly. They typically use diaphragm type compressor heads and are powered by AC or DC electric motors.

Compact compressors are devices that supply compressed air, which are typically smaller than the average industrial-grade hobo shop. The compact compressor is commonly thought to be used for inflating balloons, low pressure airbrushing or spray painting, or as an automotive accessory for inflating tires. They are usually small enough to be comfortably carried by hand, making them mobile and easy to store. While most of these superchargers are of the direct delivery type and do not have a tank or reservoir, some larger examples do. In general, these devices are of a diaphragm design, although some of the larger models have piston heads and are driven by AC or DC electric motors.

The air compressor is an indispensable piece of equipment in many domestic and industrial workshops. There they are used for tire inflation, spray painting or sandblasting, among a host of other everyday uses. The compact compressor is a lightweight member of this family that is used for low pressure spray painting, airbrush detailing and inflating balloons or toys. These devices are usually small enough to pick up and store in the back of a closet or pop into a recreational vehicle to tackle the dreaded off-road flat tire. Compact compressors typically feature operating pressures between 80 and 150 PSI (5.5 – 10 bar) and motor sizes from 1/8 to 2 horsepower (94 watts – 1.5 kilowatts).

Large compressors have a storage tank into which the compressor head pumps air for later use, while the compact compressor supplies the compressed air directly. However, some of the larger types have a small tank, averaging around 5 gallons (19 liters). The small to medium compressor will come with a regulator, compressor filter, and hose. Depending on the intended use, a range of tire inflation needles or gauges and accessories may also be included. Some compact compressor models also include a low pressure airbrush or spray gun starter kit.

Most compact compressor models are equipped with diaphragm type compressor heads. This type of compression mechanism is reliable, effective and quiet, making it ideal for use in the home or studio. Larger versions may have conventional piston type heads suitable for higher power ratings. Models intended for use in the home or workshop will typically be powered by alternating current (AC) electric motors. Those designed for use as automotive accessories are usually powered by 12-volt direct current (DC) power supplies and are often fitted with cigarette lighter-type plugs.
