Specialized Hinges

Custom Grease Containment

Fan Curb modification 

Minimized Downtime 

Proper hinges protect the thin alluminum from shearing under the weight of the fan over time and is the leading cause of fan degradatuion over time and can shorten the life a=of a fan by half.

Grease Containment Systems are not created equal. Grease overflows standard systems in and can cause serious roof damage. We install all our fans with handpicked systems that match the restaurant volume and grease type. Yes.. every restaurants type of cooking changes the consistency of the grease collected in the fan. Our grease absorbtion pillows are state of the art and neutralize the hazardous properties of the grease, and trap the grease inside. For high volume clients we arrange for monthly pillow exchanges ensurin that grease never gets on your roof

Fan Curbs need to be made to fit the fan in such a way that it can be properly opened and cleaned. There are affordable conversions we can make to just about any fan configuaration so that the fan blades can be properly cleaned and the duct can be accessed from above. This is where our expertise really comes in handy and we can ensure that even the most tricky setups work teh way they are supposed too.

We pre-prep your fan at our shop complete with electrical whips, jucntion boxes, hinges and the crucial fan access ports that allow the blades to be cleaned on both sides keeping the wheel balanced like it came from the factory. This minimizes installation time down to an hour or two iin most cases.
