A variety of Flow Restrictors and Pressure 
Regulators for the Sample Flow Method are 
available from Nuvair, all calibrated to produce a 
flow rate of 1 – 5 L/min with a Regulator output of 
100 – 160 psi. 
 
Universal Flow Restrictors are used  for most 
applications and are typically provided complete 
with Regulator. 
 
When analyzing Scuba Cylinder gases, special 
Flow Restrictors can be used to obtain the sample 
gas directly from the BC inflator hose.  A variety of 
BC Flow Restrictors are available to fit the different 
types of inflator hose QD fittings used.
