The GC01 (pn 16858) has been retired. This copper gas chamber orifice was used in conjunction with the retired HS-55 compressor. The GC01 provided bubble rates as low as 10 bubbles per minute while reducing the lag time between water level rise and the orifice pressure. Older systems could be retrofitted with the GC01.
