FAQs about the Grease Lock System

Grease Locke System "GLS" Commonly Asked Questions

Q
Is the Grease Lock Sysrem (GLS) listed by a nationally recognized testing laboratory (NRTL)?
A Yes. To satisfy fire marshals, building inspectors, and code officials, and to meet NFPA 96 and IMC requirements, the GLS testing was observed by the nationally recognized Intertek ETL laboratory. The Intertek/ETLlisting report is recorded under ETLControl Number 3190996. The Grease Lock System was tested to the UL 1046 Flame-tunnel Test and UL710 abnormal flare-uptest, thereby qualifying the GLS as a "Recognized Component" that"Conforms to UL Std 1046 & ULC-S649-06 Canadian equivalent of UL Std1046" when installed in front of a UL 1046 / ULC 649 metal baffle.
Q
With all of that grease collecting in the filters, can the Grease Lock Filters(GLF) catch on fire and will the fire spread?
A

No, the GLF will not catch on fire. The grease in the filter catches fire as it burns off but the filter itself only chars. The flames from burning grease do not move to other filters, staying contained. When the source of the flame is extinguished, so is any flame on the filter.

Q
Is the Grease Lock System certified by the National Sanitation Federation (NSF)?
A Because the Grease Lock filters are disposable, NSF certification does not apply because it only includes reusable products.
Q How often do Grease Lock filters need to be replaced?
A Replacing filters depends on the cooking device under the filter. If your cooking methods and foods use a high amount of grease, thus causing more grease particulates in the air, then the filters will need to be changed more often. Facilitec West provides an initial filter change schedule based on your needs so you aren’t guessing. Grease Lock filters do not need to be changed until they are fully utilized.
Q Is it dangerous to change a GLF myself?
A Changing filters is completely safe, and were designed to be so. With the Grease Lock mounting tool, the filters are easy to install and to remove, so you won’t need to stand on equipment to change them because of how the mounting devise is constructed. Grease Lock filters are non-toxic and perfectly safe to handle yourself. Ellis Fibre recommends that the filters be changed in the morning before the cook line is heated to keep the filters from coming in contact with hot equipment.
Q Will GLS cause any airflow problems within my vent hood?
A

No, the Grease Lock System does not interfere with airflow through the filters. Because of this, installation does not include replacing your current fan motor with a high capacity motor.

Q Will the system cut down on ductwork grease build-up?
A Yes. In fact, the GLS is designed to significantly reduce grease buildup inside the kitchen’s hood and ducts, and on your roof, saving you considerable cleaning and maintenance costs.
Q How often will I need to get my ducts cleaned with the Grease Lock System?
A In some areas, kitchen duct cleaning is determined by local regulations, so check with your AHJ (Authority Having Jurisdiction) before scheduling regular cleanings.  However, NFPA requires cleaning once there is over 1/8” of buildup in any section of the exhaust system. In general, your ductwork and extractor should be cleaned whenever buildup of grease is evident. With the Grease Lock System in place, you should notice fewer necessary cleanings.
Q Is disposal of the Grease Lock filters easy?
A Yes. The GLF fibers are biodegradable with significant benefits accruing from returning it to the earth as a fertilizer, rich in nitrogen and sulfur.(Source: Wool as a Technical Fiber, J.Text. Inst., 2003, 94 Part 3, Textile Institute) Spent filters can safely be disposed of in your regular trash receptacle.

Q
Since my fan has a drain spout on only one side, why does it need a 360-degree gutter?
A Over time, fan parts can loosen due to normal cleaning and maintenance, leaving gaps where grease can leak. A 360-degree gutter catches grease wherever it comes from, protecting your roof on all sides.
Q Will I need to buy a new Grease Gutter if I replace my fan?
A

As long as the fan is the same size and the curb is not changed, then no,you won’t need to replace the Grease Gutter because it mounts to the curb and not the fan.
