Fume Cupboard System

A fume cupboard is an enclosed ventilation system that draws air inward across the sash opening, capturing hazardous fumes and vapours before they reach the operator and exhausting them safely away.

POLYDAMIC manufactures chemical fume cupboards and laboratory fume hoods in Malaysia, built from welded polypropylene and available in tabletop or full-height configurations. Because we also manufacture the ducting, exhaust fan and scrubber, we supply the complete ventilation system rather than the cabinet alone.

Construction

Our fume cupboards are built entirely from chemical and corrosion resistant polypropylene thermoplastic, 6mm to 12mm thick, aerodynamically designed for uniform and safe airflow across the face.

All corners are smoothly bent for safety and easy cleaning. Fully welded joints eliminate the need for secondary sealants — unlike phenolic resin or epoxy alternatives, where sealant degradation is the usual first point of failure in corrosive service. With no coating to breach and no steel substrate underneath, the chemical resistance runs through the full material.

Thanks to the flexibility of thermoplastics, our fume cupboards can be custom built to suit any size, site condition or user preference.

• Ideal for cleanrooms, semiconductor industry, wet chemistry labs, pharmaceutical R&D, metal plating labs and acid digestion

A Complete Exhaust System

A fume cupboard only performs as well as the system behind it. A hood connected to an undersized fan or an over-long duct run will never reach its design face velocity — the most common reason a new installation fails its first LEV examination.

POLYDAMIC supplies every part in-house:

• Fume cupboard — welded PP, custom built
• Ducting — FRP, PVC, CPVC, PP or PVDF, matched to your chemistry
• Exhaust fan — FRP centrifugal fans, 200 to 48,000 CFM
• Scrubber — where the exhaust stream needs treatment before discharge
• DOE application and LEV assessment — consultancy in-house

A ducted fume hood is local exhaust ventilation under the USECHH Regulations 2000, and must be tested on installation and examined periodically by a DOSH-registered competent person. We specify the system to meet that from the outset.
