  • The VIROGUARD also protects your roof both between and (unlike other units on the market) during the exhaust system maintenance cleaning protecting both your roof and the environment!!! You do not have to cover or remove the unit and run the grease onto the roof like other units!!! Its your cleaning company's dream protection unit!!!
  • The VIROGUARD unit can be plumbed back into the grease stack eliminating any potential for grease leakage on roof, simply open the valve when cleaning the system and it drains back into to grease exhaust system.
  • Unit can be plumbed with a standard 1-1/2" hose bard to fit standard industrial vacuum hoses so unit can be run down to wet vac or to bucket during cleaning.
  • THE VIROGUARD unit can also be run to nearest drain with a standard 1-1/2" vac hose (not recommended unless sanitary sewer)
  • The VIROGUARD RAINSHIELD edge sits 1-2" above the base of the fan on most fans (or on the bowl on Breeder style fans) to allow grease leakage from the base of the fan to run into unit while keeping most of the rain out.
  • Seamless welded unit does not allow any grease to reach roof area.
  • The VIROGUARD fits on outside, top and into the grease exhaust stack leaving no areas unprotected and fixing most curb installation problems. No more leakage between the containment unit and the roof and no more flimsy flashings required.
  • The VIROGUARD is a convenient size to allow easy access to the grease exhaust for cleaning only extending out approx. 10" from the curb allowing servicing without having to protect or stand on the unit.
  • In extreme cases, the viroguard can be easily drained off into a bucket on the roof from the drain barb if you are late for you normal cleaning cycle. It should never need service between normal cleanings.
