ENTRY C25 RDF Combi – Sea Side

Product details

ENTRY C25 RDF Combi – Sea Side is a dry-goods filtration unit designed for pond or aquarium water treatment using a drum-based mechanical waste water filtration process. Practically, it removes debris via a drum with a controlled automatic cleaning cycle, then routes filtered flow back for reuse. The “RDF Combi” style indicates it combines mechanical drum filtration with additional biofiltration capacity (a separate bio chamber), making it suitable where both suspended solids removal and biological filtration are desired. The unit is pump-fed through a gravity/airlift/pump feeding arrangement and includes an integrated control box for automatic cleaning and flushing routines.

Features:

• Maximizes debris collection with a drum filter and adjustable rinse/flush controls.
• Automatic cleaning is plug-and-play using a stainless steel float, with manual turn/rinse options.
• Supports multiple connections for flushing and system integration (pond pump, pond pump/flushing pump sockets, and drum drive motor connection).
• Modular construction with interchangeable built-in parts for easier maintenance.
• Includes a demountable spray bar and a removable flushing channel to aid cleaning.
• Designed with a sealed housing and CNC-cut PP components, using stainless steel and silicone sealing materials.
• Provides a bio chamber with capacity for Helix bio media (90 liters, as supplied by the unit design).
