Calgaz, the world’s leading manufacturer of calibration gases and equipment, is proud to offer the most comprehensive range of specialist regulators around the globe for non-refillable and portable gas cylinders.
The FF20 series has been developed to precisely fit the 1AL aerosol type cylinder. Calgaz offers four variations of the FF20.
The Septum Model allows gas to be withdrawn by syringe as required. The Stem Flow and Flow Meter versions are fitted with a flow rate indicator using a floating ball indicator with a higher minimum flow rate. The Stem Flow is also equipped with a small inlet pressure gauge to allow the user to estimate the volume of gas remaining in the cylinder. Calgaz can also offer a Nozzle, a push fit onto the 1ALU cylinder.
All regulators carry a 24-month warranty, and we recommend replacing them after two years of service.
