Nuvair manufactures Gas Analyzers for the Diving, Medical, Safety, Industrial and Government sectors.

We offer several flow restrictors and meters for use with gas testing, analyzing, compressor construction and gas panel construction.





Adjustable Flow Restrictors (Part# 9520G INT or DIN)
Reduces pressure from 3000 PSI to 120 PSI and the flow is adjustable from 0 to 8 Liters per minute (LPM) in .5 LPM increments. Available with International or DIN Yoke. These restrictors are used with scuba bottles.



Part# 9518-SCUBA PRO, 9518-STD, 9518-MARES
We offer a range of gas restrictors for attaching your BC inflator hose to Nuvair Analyzers. These flow restrictors are used to reduce gas pressure from a scuba cylinder to our Pro O2 and Pro CO Analyzers.



In-Line Flow Restrictor ¼" FNPT by 3/16" Barb (Part# 9518)
We offer a range of gas restrictors for attaching hoses to Nuvair Analyzers. These flow restrictors are used to reduce gas pressure to our Pro O2 and Pro CO Analyzers.



Flow Meter (Part# VFA-24-BV)
Flow meters and regulators are used for accurate flow restriction on panels. A flow meter must be used with a regulator to reduce the input pressure below 100 PSI.



High Pressure to Low Pressure Regulator (Part# 9519)
High Pressure to Low Pressure regulator with flow restrictor used in panels and in-line on compressors for our Pro series analyzers. The regulator reduces pressure from 6000 PSI to 120 PSI and then the restrictor restricts flow to 1 liter per minute.
