Kitchen Grease Filter Safety and Installation

Kitchen Grease Filters Explained: Restaurant Exhaust Safety

Kitchen grease filters are one of the first lines of defense for restaurant safety. Kitchen grease is highly flammable, therefore replacing and maintaining a restaurant’s grease filters is an important step in reducing the risk of kitchen grease fires.

Most people think of grease as a liquid, but grease can also travel by vapours and smoke. If the exhaust effluent is properly filtered, a large percentage of this grease is removed from the air stream. This not only greatly reduces the amount of grease that will stick to the inside of the kitchen exhaust hood, it also reduces the risk of a grease duct fire and the need for kitchen exhaust cleaning.

How do Shepherd Filters help keep grease out of the exhaust system?

Shepherd Filters work by stopping more grease at the source. When grease vapours and smoke rise into the kitchen hood, Shepherd Filters help capture airborne grease before it moves deeper into the exhaust ductwork. The material of the filter traps the grease at the hood, making the exhaust system cleaner and easier to maintain. When it is time for a change, the used filter can be removed and disposed of, and then easily replaced with a new filter.

What are Shepherd Filters made from?

Shepherd Filters are disposable kitchen grease filters made from 100% wool, which is naturally flame-resistant and bio-degradable. It is, therefore, safe to dispose of in your regular waste bin!

Because wool fibres break down, it is the obvious choice for anyone concerned about the environment (and much safer to use than cleaning chemicals).

Wool may be ignited if subjected to a significantly powerful heat source, but does not normally support flame and will instead smoulder, usually only for a short time.

Wool’s flame-resistant properties make it an ideal fibre for kitchen grease filters, helping to reduce the risk of fire spreading.

Wool is also a fabulous product for absorbing oil (grease).

Wool has the right properties for the job!

Is wool fire resistant?

Wool is an excellent fibre when it comes to fire safety as it is naturally flame-resistant.

Wool may be ignited if subjected to a significantly powerful heat source, but does not normally support flame and will instead smoulder (usually only for a short time).

Will Shepherd Filters affect airflow?

Shepherd Filters capture up to 98% of airborne grease before it enters the exhaust duct without restricting airflow, when the wool filter media and frame are used together.

Easy to use, our products come with the peace of mind that they have been:

• Airflow tested
• UL1046 flame barrier tested; and
• HACCP approved

Shepherd Filters is the result of many years of development, receiving the UL 1046 standard in 2006, as well as AS1668 and NFPA 96. Shepherd Filters is patented in the USA, Australia and New Zealand. It is protected in numerous countries due to the specific natural formula of the product in regards to weight and loft. This formula optimises the capture and containment of grease particles without a restriction of airflow to the exhaust hood system. Click below for a copy of our:

SPECIFICATION SHEET – SHEPHERD FILTERS

Can Shepherd Filters be installed in an existing hood?

Yes, filters are designed to retrofit to existing kitchen hoods.

How do you change a Shepherd Filter?

Here is a quick demonstration on how a Shepherd Filters kitchen grease filter is replaced:

How often should these grease filters be changed?

The short video below covers several factors that determine how often Shepherd Filters will need changing:

Three fundamental factors include:

1) Hours of operation
2) Style & volume of cooking; and
3) Equipment in use

Although changing may be more frequent for some filters (and less for others), it takes just a few minutes a day.

Ultimately, filter usage and costs relate directly to your business’ turnover, saving you money and reducing your fire risk!

NFPA 96 FIRE CODE FOR HOOD GREASE FILTERS OR 'GREASE REMOVAL DEVICES'

The National Fire Protection Association (NFPA) Code 96 is the standard for ventilation control and fire protection of commercial cooking operations.

Below we have listed some of their fire safety codes described in NFPA Code 96, specifically for kitchen grease filters:

Filters shall be arranged so that all exhaust air passes through the grease filters.
Filters shall be listed and constructed of steel or listed equivalent material.
Filters shall be of rigid construction that will not distort or crush under normal operation, handling, and cleaning conditions.
Filters shall be easily accessible and removable for cleaning.
Filters shall be installed at an angle not less than 45 degrees from the horizontal.
Listed kitchen grease filters, listed baffles, or other listed grease removal devices for use with commercial cooking equipment shall be provided.
Listed kitchen grease filters and grease removal devices that are removable but not an integral component of a specifically listed exhaust hood shall be listed in accordance with UL 1046.
Mesh filters shall not be used unless evaluated as an integral part of a listed exhaust hood or listed in conjunction with primary kitchen grease filters in accordance with UL 1046.

SHEPHERD FILTERS ARE WIDELY USED ON A GLOBAL SCALE
