Plastic clamp-on GOCO nozzle for 1" Schedule 40 blowtube. Clamps straight onto the tube – no welding and no threaded socket needed – so it suits retrofitting an existing blowtube as readily as a new one.

A GOCO nozzle balances the flow through every hole along the blowtube and aims the pulse jet squarely into the filter, so the pressure drop through the blowtube holes stops eating the pulse. That lets the system run at an An/Ap ratio (total blowtube hole area to blowtube cross section) of up to 1.5, where a blowtube with plain drilled holes typically manages only 0.5 to 0.8 – which is the difference between using the diaphragm valve’s full pulse and wasting most of it.

Before fitting: drill a 22.0 mm (0.866") hole in the blowtube, drill the nozzle itself to the orifice size your system needs, and make sure the o-ring is in place when the nozzle goes onto the pipe.

Temperature limit: plastic nozzles are not suitable above 80°C (176°F). For hotter gas use the aluminium clamp-on nozzles, which are rated to 400°C.

Setting the nozzle height. For best performance set H, the distance from the nozzle to the filter, using H = (Ø Filter − 48) / 0.353 in mm, or H = (Ø Filter − 1.88) / 0.353 in inches.

Not for gas turbine applications. Goyen specifically excludes the GOCO nozzle range from gas turbine service.
