Complementing our gas cylinders, we have a range of our own gas pressure regulators. The Spanreg Fixed flow regulator is designed to supply constant flow rates, ranging from 0.25 LPM to 6 LPM pre-selected with order. The user gets an accurate flow rate of gas mixture from Maxi Spancan (A110) or GAL range of Portagreen cylinders, even as the internal cylinder pressure drops. The back pressure is 4.1 bar (60psi) so that flow control is achieved until the cylinder is nearly empty @ 1.2bar. The regulator provides a constant reliable flow, while maximising the lifetime of the cylinder and minimising wastage. Being easy to turn off and store, therefore avoids accidental leakage through not turning the regulator off fully after use. The Spanreg FF provides a very cost- effective solution.
