The HSE definition for breathing apparatus is that they use a supply of breathing quality gas from an independent source, such as air compressors or compressed gas cylinders. In this case compression of the supply gas at some stage is implied. Both respirators and breathing apparatus are classed as respiratory protective equipment by the HSE. [2]
See: venturi mask air-filtering respirator An air-filtering respirator is a breathing apparatus which removes particulates from the ambient air by passing it through a filter. air-purifying respirator An air-purifying respirator is a respirator which uses a filter, cartridge, or canister to remove specific air contaminants by passing ambient air through the air-purifying component ...
The Oxygen breathing apparatus (OBA) is a closed circuit oxygen rebreather. used primarily in firefighting by the US Navy. Its oxygen is generated by chemicals contained in the green canister, which is inserted at the base of the breathing device.

Paul Hashagan also notes that, in 1863, A. Lacour developed and patented the "improved breathing apparatus". This system provided air to the wearer from two canvas and rubber balloon-like bags which were carried on the wearer's back. A pair of bellows would then allow the wearer to pump air to a mouthpiece.
Test bench for a miner's closed circuit self-rescuers. A self-contained self-rescue device, SCSR, self-contained self-rescuer, or air pack is a type of closed-circuit SCBA [1] with a portable oxygen source for providing breathable air when the surrounding atmosphere lacks oxygen or is contaminated with toxic gases, e.g. carbon monoxide.
A breathing hose or sometimes breathing tube on a rebreather is a flexible tube for breathing gas to pass through at ambient pressure. They are distinguished from the low-, intermediate-, and high-pressure hoses which may also be parts of rebreather apparatus.
