HADPRO can install the hinge kits necessary to protect your investment in your upblast fan and to make it NFPA 96 compliant.
Hinge kits are required on all upblast fans according to NFPA 96 Standard 126.96.36.199. A hinge kit is very similar to a door hinge, and it allows an upblast fan (pictured) to fold open safely and easily so that technicians can clean the underside of the fan and the ductwork beneath the fan. Without a hinge kit, technicians must completely detach the fan from the duct on each service and set it on the roof. This can cause a number of problems including:
- Bent base plate of the fan or the duct work, which can cause gaps that allow grease to leak onto the roof and damage the roof or allow precipitation into the duct work and even into the kitchen. A loose connection between the fan base plate and duct work can also cause the fan to rattle, making noise and reducing the life of the fan.
- Damaged fan wiring, due to stretching when removing the fan from the duct work and placing it on the roof.
- Damaged roof and/or leaks, due to placing the fan on the roof repeatedly for cleaning and maintenance.
HADPRO helps its customers avoid this problem by installing hinge kits on up blast fans. Protect your equipment, your roof, and maintain your NFPA 96 compliance by having HADPRO install a hinge kit on your up blast fans.
Top 3 Frequently Asked Questions about Exhaust Equipment
Can HADPRO install a hinge kit on non-standard up blast fans? What about hinge repairs?
Non-standard installations such as tapered duct work, fan base plate overhangs, elevated fans on angled roofing, and horizontally mounted fans are all problems HADPRO can solve with a custom hinge kit installation. HADPRO can also do hinge kit replacements and repairs, provided your hinges are not welded on and your fan is not welded shut. Give us a call and let us help you today!
What’s the proper way to clean a fan? What kind of fan do I have?
Fan cleaning technique varies according to the type of fan installed at the facility. HADPRO technicians are trained to clean all fan types including up blast fans, in-line fans, utility set fans, etc. In cleaning a fan, technicians always clean the entire accessible portion of the fan, as well as the duct work below the fan or feeding into the fan. Chemical degreasing, pressure washing, and magnetic scraping are all used according to the fan type, amount of grease buildup, fan condition, and the technician’s discretion.
What is the difference between a dry scrubber and a wet scrubber?
Dry scrubbers and wet scrubbers both remove particulate matter (like grease vapors) from exhausted air flow. Dry scrubbers do this with disposable filters, which must be replaced to maintain their filtering efficiency and prevent the filters from becoming fire hazards themselves as grease builds up. Wet scrubbers remove grease matter by passing exhausted air flow through a spray of ionized water particles that bond to the grease in the air. Wet scrubbers tend to be more effective at removing fine particulates, but have relatively high maintenance costs and must be protected from freezing if located outside.
