line and duct burners
NP-RG AIRFLO®
MAXON Series NP & RG AIRFLO® burners consist of a robust cast-iron or aluminum burner-body (which serve as the gas manifold) drilled to discharge the gaseous fuel between diverging stainless steel mixing plates.

Overview
MAXON Series NP and RG AIRFLO® Industrial Burners provide clean, direct fired air heating to optimize process air heating efficiency. The modular natural gas burners install easily with custom built patterns to fit your duct. NP and RG burners burn cleanly with most gaseous fuels and offer high heat releases per foot with wide turndown ratios.
Features & Benefits:
Features & Benefits:
- For direct fired fresh air heating applications
- Operates economically (100 % thermal efficiency) and installs easily
- Burns clean and odor-free with most gaseous fuels, meeting or exceeding most known standards for direct-fired make-up air and space-heating applications
- High turndown, up to 25 : 1
- Modular design configured within your duct for optimal temperature distribution
- No need for a combustion air blower
- Extremely low maintenance cost thanks to robust design (no moving parts) and high quality materials
