the operating pressure of drain clearing compressed air device 10 is typically between 0 3 0 45 mpa the safety pressure of fine tuner 86 is 0 45 0 55 mpa fine tuner 86 adjusts the pressure of spring 88 using a screwing action when the inner pressure of compressed air storage chamber 14 exceeds the safety pressure of fine tuner 86 spring 88 cannot be compressed by trigger piston 66 and jam core 90 will be jammed excess pressure is then released from plug 84 and fine tuner 86 to ensure safe usage of drain clearing compressed air device 10 no adjustments to pressure release safety component 80 are needed since it is manufactured to maintain the required air pressure referring now to fig9 there is depicted a detachable drain sealing adapter to be used with the drain clearing compressed air device for unclogging sinks basins referring now to fig1 there is depicted a detachable drain sealing adapter to be used with the drain clearing compressed air device in conjunction with the adapter to unclog sinks basins shown in fig9 for unclogging open surface drains bathtubs or toilets referring now to fig1 there is shown another detachable drain sealing adapter to be used with the drain clearing compressed air device for unclogging sinks basins referring now to fig1 there is depicted another detachable drain sealing adapter to be used with the drain clearing compressed air device for unclogging sinks basins referring now to fig1 there is depicted another detachable drain sealing adapter to be used with the drain clearing compressed air device for unclogging surface drains or bathtubs referring now to fig1 there is shown another detachable drain sealing adapter to be used with the drain clearing compressed air device for unclogging surface.
