Frequently Asked Questions

ViroGuard is only cleaned during your normal exhaust cleaning cycle (quarterly for most restaurants). There is no special maintenance schedule for ViroGuard.

Absolutely not. Unlike all other units on the market, ViroGuard can be cleaned without running grease onto the roof. The roof is protected before, during, and after cleaning.

There are no ongoing costs or charges. Once you install ViroGuard, your rooftop grease problem is solved. Just have your cleaning company clean it at the same time they clean the exhaust system. In fact, it should save you money on roof cleanup since all grease and cleaning solution is contained — especially in below-freezing weather.

ViroGuard does not require any servicing other than normal cleaning. There is nothing to inspect or replace on a regular basis.

Made of 304 stainless steel, ViroGuard will last a lifetime. Barring some unforeseen disaster, it should never need to be replaced.

No pads or diapers are needed. ViroGuard is a self-contained unit that holds the grease until it is drained. No grease ever gets on the roof.

Any competent HVAC contractor can install the unit easily by following our step-by-step installation guide using basic tools. Installation also includes re-wiring the fan.

The installation process includes extra-strength stainless steel Virospec hinges that ensure your fan will not be damaged during exhaust cleaning.

Installation includes re-wiring. This is handled as part of the standard installation process.

NFPA 96 specifies cleaning frequency based on cooking volume and type. High-volume or solid fuel cooking operations typically require monthly cleaning. Most full-service restaurants require quarterly cleaning. Lower-volume operations may be cleaned semi-annually or annually. Enviromatic will assess your operation and recommend the appropriate schedule.
