The Klargester 4000L Grease Separator (NSG09) is a reliable and efficient solution for removing fats, oils and grease (FOG) from wastewater before it enters the drainage system. By allowing grease and fats to naturally separate from wastewater flow, the separator helps prevent blockages, protect drainage infrastructure and improve the overall performance of downstream treatment systems.

Ideal for commercial food preparation environments, the Klargester NSG09 is suitable for small canteens, pubs, cafés and catering facilities, as well as larger applications including commercial kitchens, hotels and restaurants. Installed close to the source of contamination, it provides a hygienic and effective method of grease management while helping businesses remain compliant with best drainage practices.

 

Why Choose the Klargester NSG09?

Grease accumulation is one of the leading causes of drainage failures in commercial kitchens. The Klargester 4000L Grease Separator intercepts fats and grease before they can enter the drainage network, helping to reduce maintenance costs, minimise downtime and protect wastewater treatment systems.

Manufactured to meet the requirements of BS EN 1825-1, the NSG09 offers dependable long-term performance for a wide range of commercial and industrial applications.

Important Installation Information

For optimum performance, the grease separator should be installed as close as possible to the source of contamination and selected according to the expected wastewater flow rate and discharge temperature.

Please note: The Klargester NSG09 Grease Separator is supplied without a manhole cover and frame. As covers are dependent on the installation location and required loading class, these must be purchased separately once the installation details have been confirmed (pedestrian areas, driveways, heavy-duty traffic zones, etc.).

Whether you're operating a busy restaurant, hotel kitchen, pub or catering facility, the Klargester 4000L Grease Separator provides reliable grease separation, helping to protect your drainage infrastructure, reduce maintenance costs and ensure efficient wastewater management.
