Frequently Asked Questions
Practical support guidance covering operation, maintenance, servicing, troubleshooting, installation and product performance.
Daily operational checks and routine maintenance are recommended to support optimal grease separation performance and long-term reliability.
GreaseShield® systems are designed to minimise pump-out requirements through automatic grease and solids removal technologies.
Poor grease separation can be caused by insufficient maintenance, incorrect operational settings, damaged components or excessive food waste entering the system.
Odours are commonly caused by inadequate cleaning, food waste build-up or poor maintenance routines. Regular servicing and basket cleaning are recommended.
Solids baskets should typically be checked and cleaned daily depending on kitchen usage, food waste volumes and operational demands.
Back-ups may indicate downstream blockages, excessive food waste, insufficient maintenance or restricted drainage flow conditions.
FilterShield™ systems are designed to capture food solids before they enter drainage systems, helping reduce blockage risks and drainage disruption.
EPAI provides installation guides, technical specifications, operational manuals and maintenance documentation across the product range.
GreaseShield® utilises waste thermal energy already present within commercial kitchens rather than relying on traditional heater elements.
EPAI technologies are designed to support reduced energy consumption, lower maintenance requirements and improved wastewater management performance.
Various GreaseShield® models are supported by certifications including EN 1825, ASME, CSA, PDI and environmental certifications depending on model and region.
EPAI technical support teams are available to assist with troubleshooting, servicing support, installation guidance and operational assistance.

Frequently Asked Questions
Fats, oils, and grease (FOG) typically come from a variety of sources, including:
1. Cooking: Fats and oils used in cooking, frying, baking, and grilling can easily become FOG when they cool and solidify.
2. Food waste: Leftover food scraps that contain fats and oils can contribute to FOG buildup when washed down drains.
3. Meat products: Fatty meats, such as bacon, sausage, and beef, can release fats when cooked and washed.
4. Dairy products: Butter, cheese, milk, and other dairy items can contain fats that contribute to FOG when washed down drains.
5. Sauces and dressings: Salad dressings, gravies, mayonnaise, and other condiments often contain oils and fats that can solidify in pipes.
6. Food processing: Food manufacturing facilities can produce significant amounts of FOG as a byproduct of their operations.
FOG can accumulate in sewer systems and cause blockages and backups if not properly managed. It’s important for individuals and businesses to dispose of FOG responsibly, such as by collecting it in grease traps or interceptors and disposing of it properly rather than pouring it down drains.
Food waste solids and FOG are eliminated by GreaseShield® in four steps:
- Food Solids Removal: As wastewater enters the unit, an auger or pre-filter screens and dewaters the food solids, which are subsequently placed in an external container.
- Grease Separation: Baffles, reverse flow, and thermal layers are used to separate FOG using waste heat energy prior to its solidification.
- FOG Removal: Oil is drawn to and extracted by a semi-submerged oleophilic roller, which is then scraped off and transferred into an external container for disposal.
- Self-Cleaning: The device reuses grey water to eliminate sedimentation, reducing standing water and unpleasant aromas. It also does routine internal washdowns and circulation pump activations.
A constant, maintenance-free functioning and optimal kitchen efficiency are guaranteed by this effective method.
GreaseShield® can be placed in a range of kitchen configurations, from compact prep sinks to larger spaces with ovens and dishwashers. It needs to be mounted above ground, preferably next to linked appliances or beneath the sink, and 1.5 meters away from a dedicated 5 amp power outlet.
GreaseShield® is made to last; after 10 years, some units are still in use. There is a 10-year guarantee on the stainless-steel cabinet (excluding purposeful and unintentional damage). It is advised to have quarterly maintenance procedures performed to guarantee longevity and peak performance. For efficient and routine maintenance, EPAS provides a managed service package. Upgrade options are available for inoperable or outdated systems.
Some local authorities such as Dublin county council require grease traps/interceptors to be serviced and maintained every quarter. In this case, EPAS can offer competitive quarterly preventative maintenance which will ensure that the GreaseShield® is maintained by the local authority guidelines and is working efficiently and effectively.
Yes, GreaseShield® requires very little upkeep every day. At the end of the day:
- Take out the food waste basket, empty it, and give it a wash in warm, soapy water.
- Using the included spray pistol, clean the PreFilter or FilterShield and swap it out for an extra basket.
- Take out the FOG collecting container, note how much FOG was taken out, and then pour the contents into a storage barrel.
- Reinstall the container onto the GreaseShield® after cleaning it with warm, soapy water and the wiper blade.
Upon installation, our engineers can provide staff training to all relevant staff plus every unit does come supplied with laminated posters showing the process. Alternatively, and more cost-effectively a video link showing the daily maintenance procedure is also available by clicking the following video.
