Space-saving hopper venting

HOPPERTOP is the perfect solution for weigh hopper venting in concrete batching plants combining a particularly small footprint with advanced dust filtration technology.

HOPPERTOP is a compact, cylindrically shaped venting filter for installation on weigh hoppers in concrete batching plants and, in general, where limited space is an issue.

Function :

• HOPPERTOP is suitable for discontinuously, mechanically filled hoppers.
• Dust collected from the air flow by a single WAM cartridge filter element drops back into the hopper after the reverse action of a compressed air pulse air jet generated by an integrated automatic cleaning system has removed the dust particles from the media. A hinged top cover protects the filter from weathering.

Features :

• Filter surface: 1.4 m2 (15 sq ft)
• Air volume: up to 140 m³/h (82 cfm)
• Cartridge filter element
• Compressed air pulse-jet cleaning system (4 bar)
• Stainless-steel casing with bottom flange
• Compact design
• High filtration efficiency of WAM filter element
• Quick, tool-free filter element replacement
• Easy installation and retrofitting

Benefits :

• High filtration efficiency
• Low emission level due to B.I.A.-certified filter media
• Small footprint: 0.06 m2 (0.65 sq ft)
• Corrosion-free design
