Duct Reducer 6 in x 4 in
The Nordfab reducer connects a six-inch duct to a four-inch duct in a straight configuration. It uses a Quick-Fit clamp-together end type for fast assembly without welding. The galvanised steel body is rated for temperatures up to 390 Degrees F and pressures up to 42 in wc.
Quick-Fit clamp system
The clamp-together connection allows sections to be joined or removed by hand without special tools. This reduces installation time and makes future layout changes simple. The 22 ga steel thickness keeps the joint rigid while staying light enough for overhead mounting.
Pressure and temperature limits
Maximum operating pressure is 42 in wc and maximum temperature is 390 Degrees F, so the reducer suits typical dust-collection and fume-extraction systems. It is not rated for high-pressure compressed-air lines or processes exceeding the stated temperature. Buyers needing higher pressure ratings or different diameter steps must select another model.

Questions about this item
Will the galvanized steel reducer need replacement if exposed to temperatures near its 390 Degrees F maximum rating?
The reducer is rated for continuous operation up to 390 Degrees F; sustained exposure above that limit can degrade the galvanized coating and require replacement.
What pressure limit should I watch for in a high-static system using this 22 ga reducer?
The maximum pressure rating is 42 in wc; exceeding this static pressure can cause deformation or joint failure on the 22 ga galvanized steel body.
How much heat does the reducer add to the airstream when the system runs all day?
The galvanized steel construction does not generate heat; it simply conducts the airstream temperature, so any temperature rise comes from the process air, not the reducer itself.
