The Africa Tanks 450mm Screen Filter is a specialized pre-filtration component designed to sit directly beneath the manhole lid of your water tank. As the primary defense against organic contamination, it effectively traps leaves, twigs, and larger wind-blown debris before they can enter the tank. By keeping organic matter out, it significantly reduces the development of sludge and prevents foul odors, ensuring your stored water remains clear and hygienic.
Key Performance Features
- Industrial-Grade Stainless Steel Mesh: Features a fine-aperture mesh that captures small organic particles while allowing for maximum water flow-through during heavy South African thunderstorms.
- Integrated Pest Barrier: The mesh is fine enough to prevent mosquitoes and other insects from entering the tank to breed, protecting your household's health.
- UV-Stabilized Polyethylene Frame: The outer ring is manufactured from high-quality, UV-protected LLDPE, ensuring the filter won't become brittle or crack when exposed to direct sunlight.
- Easy-Lift Maintenance Design: Engineered for tool-free removal, allowing you to quickly lift the screen, discard collected debris, and rinse it clean in seconds.
Ideal Applications
- Residential Rainwater Harvesting: An absolute necessity for any tank connected to a gutter system to prevent "leaf-rot" from affecting the water quality.
- Pump Protection: By removing solids at the point of entry, the filter prevents debris from clogging the suction lines of your pressure pump or damaging irrigation nozzles.
- Drinking Water Backup: Essential for maintaining the clarity and freshness of water intended for domestic use or livestock watering.
Product Benefits
- Prevents Nutrient Buildup: By stopping leaves from rotting inside the tank, the filter lowers the nutrient load that otherwise fuels algae growth.
- Precision Fit: Specifically designed to drop into the standard 450mm manhole opening found on most Africa Tank vertical and slimline models.
- Seamless Integration: Sits flush with the top of the tank, ensuring the manhole lid can still be securely locked or screwed into place.
Pro Tip: To ensure your harvesting system operates at 100% efficiency, check your screen filter after the first heavy rain of the season. If you have overhanging trees, a quick bi-weekly check will prevent water from "backing up" and spilling over the top of the tank because of a clogged mesh.
