ARKA F405H-8 manufacturer product reference

Product overview

ARKA F405H-8 4 Inch Five-Unit Automatic Disc Filter Bank is offered for application-based water-system selection in Sabah. Water passes through multiple H-Type disc units connected to common manifolds. The configured controller and three-way valves reverse flow through one unit at a time for cleaning. Match the model to the required water quality, pipe connections, operating pressure and flow. SWFI can review the stated model and site requirements for quotation; the final supplied configuration is subject to confirmation.

Technical information

Manufacturer reference: ARKA F405H-8 SELECTED MODEL — source-checked catalogue/web data Five 4 inch units; manifold 8 inch / 200 reference; catalogue maximum flow 320 m³/h; L/H/T/R/S/W/E/F 1535/1650/290/655/1310/1220/380/990 mm. SOURCE DIFFERENCE / IDENTIFICATION NOTE The manual uses row F405-8 and T=325 mm; catalogue F405H-8 gives T=290 mm. Confirm the project drawing. SYSTEM MANUAL REFERENCE Working-pressure example 0.2–1.0 MPa; water temperature below 70°C; pH 5–11.5; filtration range 20–400 µm. Grade-dependent minimum backwash: 200–130 µm, 1.8 bar and 2.5 L/s; 100 µm, 2.5 bar and 3.1 L/s; 50–20 µm, 3 bar and 3.3 L/s. Controller example 220 V and solenoid 24 V; confirm the supplied electrical configuration. The manual specifies water service and excludes hazardous liquids and food-use liquids. The selected project drawing and component ratings govern the final assembly. See gallery technical sheets for model-family tables, connection drawings and head-loss/performance curves. Ratings are manufacturer references, not guaranteed duty at every water quality. Confirm the exact material, filtration grade where applicable, flow, pressure, temperature and installation drawing.

Selection information

Required flow and operating pressure
Water source, solids load and chemical/material compatibility
Pipe connection and dimensional clearance
Filtration grade or valve function appropriate to the downstream duty
Maintenance access and control/backwash provision where applicable
