Sea Side Aquatics Entry C25 LOW Combi Filter RDF 6,600 GPH 75 Micron

Cleaner Pond Water With the Sea Side Aquatics Entry C25 LOW RDF Filter

Tired of murky water and constant manual maintenance? Your pond deserves crystal-clear results without the daily grind. This gravity-fed combi unit pulls dirty water in, spins it through a rotating drum that traps debris down to 75 microns, and flushes the waste away on its own. What's left flows into an air-powered fluidized media bed that oxygenates and cleans biologically, giving you mechanical and biological filtration in one automated body.

• Filtration Method: Combines a rotating drum filter with biological media in one automated unit.
• Debris Removal: Traps particles down to 75 microns using a 120 micron stainless steel 316 sieve panel.
• Self-Cleaning: Automatic rinse function flushes waste out on its own, with no manual scrubbing needed.
• Biological Media: Bio chamber holds 90 liters of Helix and also accepts Matala Mats.
• Aeration: 2 x air bars keep the media bed oxygenated for steady bacterial action.
• Flow Capacity: Handles up to 6,600 GPH on a gravity only feed, no pump pressure required.
• Setup Height: Installs 17 cm above water level with 2 x 4" inlets and 1 x 4" outlet located along the base.
• Control Box: Plug and play automatic cleaning with a stainless steel float, plus manual turn/rinse options.
• Pump Protection: Standard dry run protection guards your pond pump.
• Build Quality: Modular PP housing with stainless steel 316/304 parts, quickly interchangeable for easy servicing.
• What's Included: K1 media, external cleaning pump, lid, and control box come with the unit.

Rotating Drum and Biological Filtration

Two proven filtration methods work back to back inside a single housing. First, water meets the rotating drum filter, then it moves into the living heart of the system for biological breakdown.

• 38 cm x 40 cm drum fitted with a 120 micron stainless steel 316 sieve panel for fine mechanical separation.
• Debris captured down to 75 microns, keeping visible dirt out of your pond.
• Perforated sieve walls form the drum compartment for effective mechanical separation.
• 2 x 90 mm drum bypass to handle water flow safely.
• Bio chamber holds 90 liters of Helix media, sitting beneath a black media dome, and also accepts Matala Mats.
• 2 x air bars push air through the fluidized bed, adding oxygen while feeding the biological process.

The result is water that is not only visually clear but biologically balanced, since beneficial bacteria in the moving media convert harmful waste as water passes through.

Automatic Self-Cleaning System

No more scrubbing panels by hand. An automatic rinse function detects when the drum needs attention and flushes trapped debris out through the waste line, keeping performance steady around the clock.

• Includes the required stainless steel external cleaning pump, which sits standing upright on its black circular pump base cover, for flushing.
• 40 NM drive motor turning the drum at 2.5 rpm.
• 110 mm waste water outlet carries dirt clear of the system.
• Demountable spray bar with red clamps and a removable flushing channel for straightforward servicing.
• Air bar connections feed the aeration bars inside the bio chamber.

Plug and Play Control With the Sea Side Aquatics Entry C25 LOW Combi Filter

The control box takes the guesswork out of running your filter. Fit it, connect your pumps, and let the stainless steel float manage cleaning automatically.

• Automatic cleaning in plug and play mode with a stainless steel float.
• Manual turn / rinse control when you want direct command.
• Adjustable turn / flush time and adjustable rinse level.
• Dedicated sockets for the flushing pump, pond pump and drum drive motor.
• Standard dry run protection shields your pond pump.

Gravity Fed Flow in the Sea Side Aquatics Entry C25 LOW Drum Filter

Built to run on gravity only, this unit handles a maximum flow of 6,600 GPH without relying on pressurized feeds. Set it up correctly and water moves through by design.

• Installation height 17 cm above water level.
• 2 x 4" inlets and 1 x 4" outlet, positioned along the base, with standard inputs and outputs according to drawing.
• Comes fitted with a lid to keep the interior protected.

Modular Build Quality in the Sea Side Aquatics Entry C25 LOW Pond Filter

Every component is designed to be replaced quickly. Parts are built in modules, so swapping a piece is fast and simple rather than a full teardown.

• Housing in PP 8 mm / PP 15 mm with a PP 20 drum.
• Stainless steel 316/304 components and a silicone seal.
• PP casing cut with a CNC machine for precise fit.
• Modular parts are quickly interchangeable.
