Systems and methods for pneumatic cleaning of an extraction system filter

A pneumatic filter cleaning device for an airborne extractor system comprising:

• a nozzle secured to a first end of a conduit;
• a chamber enclosing a movable guide that is coupled to a second end of the conduit, wherein the nozzle is configured to release a pulse of air when a pressure at the nozzle reaches a threshold pressure level,
• wherein the conduit is configured to be forced to extend to a first position in response to an increase in pressure at the nozzle without the use of a spring, and wherein the conduit is configured to be forced to retract to a second position in response to release of the pulse of air without the use of a spring;
• and
• a valve configured to convey pressurized air into the filter cleaning device in response to a control signal from control circuitry,
• wherein the conduit is configured such that a change in pressure at the chamber or the nozzle forces the nozzle to release the pulse of air thereby rotating the nozzle as the conduit moves from the first position to the second position, and
• wherein the movable guide is configured to regulate rotation of the nozzle.
