Sherwood's 50 years in the regulator business have allowed them to create the SR1, a regulator that has a breathing performance of less than 0.5 joules/litre, at 50m with a 62.5 RMV. Both the SR1 first and second stage are pneumatically balanced for super smooth gas flow regardless of depth or cylinder pressure. A two piece flow through first stage design allows for precise control of the intermediate pressure allowing the second stage to work correctly at any cylinder pressure.
The first stage is environmentally dry sealed, this stops anything from entering or leaving the regulator. This means contaminants cannot get inside the regulator to cause a freeflow and it also means that water does not get inside to cause corrosion. The first stage is fitted with a 360 degree swivelling turret that has five medium pressure ports, allowing for ultimate flexibility of hose routing. Two high pressure ports allow the use of a transmitter along side a traditional pressure gauge.
The second stage is fitted with both a cracking resistance control and venturi control, both of which are controlled with one knob. This means with one movement the regulator can be detuned to avoid freeflows at the surface and underwater, moving the control the other way retune the regulator back to top-notch performance, all in a couple of seconds. The SR1 second stage is fitted with a SMART demand level and crown, when the regulator is depressurised the valve seated is lifted off, reducing unnecessary wear during storage.
