What this box-type drum actually does It’s your solids gatekeeper. Water enters the box, hits the stainless screen, and fines around ~74 μm get stopped before they ever reach bio or UV. A small controller watches the line and kicks off backwash by level (rising head across the screen) and by time (your set interval), so the mesh stays open during busy hours.
Body + screen, built for wet rooms The housing is PP—light, corrosion-resistant, and happy in freshwater, brackish, or marine bays—while the rotating screen is stainless. That combo keeps the structure from rust dramas and gives the screen the stiffness it needs to hold mesh accuracy.
Where it lives in the train (and why) Park it at the front of the filtration module: drum → bio → (skimmer if used) → UV/ozone. Catching solids first protects nitrification and keeps the UV sleeves from fouling, which is exactly how the modular RAS layouts in the file are arranged.
How you size it without guesswork The catalog maps flow to models and pipework:
Controls that actually help operators
-
-
Dual triggers keep cleaning predictable: level-based washes catch sudden load spikes; time keeps the screen tidy between them.
-
Clean drum = steady hydraulic head = happier bio and stable UV dose downstream. (This coupling shows up across the RAS notes.)
What “intensive” means here You’re running higher biomass and feed, so fines build fast. A box-type drum with automatic wash logic buys you two things: fewer hands in the pit during peaks and a more stable flow to the bio/UV stages. The spec’s ~74 μm baseline is set exactly for that role.
Interfaces and add-ons Standard inlet/outlet sizes match the model (see above). Backwash has its own discharge line—route it to waste, not back to the loop. If you’re bundling with a skimmer or UV, the same interface logic used across the modular blocks keeps the hand-offs clean.
