Corrosion-resistant exhaust systems for acids, caustics, and solvent fumes—engineered for uptime.
AJR designs and installs corrosion-resistant ventilation duct for harsh process environments. We integrate fans, stacks, dampers, access doors, and supports with the right materials and velocities to safely move contaminated air out of production spaces.
Our teams work inside live plants with disciplined permits and QA/QC. We match media and temperature to materials like FRP and thermoplastics (PVC, CPVC, PP, PVDF) and deliver complete systems that include capture points, risers, headers, fan transitions, stacks, and discharge. Each project is balanced, tested, and documented for long-term reliability.
FRP and thermoplastic duct sized for transport velocity, temperature, and chemistry; elbows, tees, reducers, and transitions detailed to minimize losses.
Corrosion-resistant fans, isolation and volume control dampers, backdraft protection, stack design and discharge height per site requirements.
Bench hoods, canopy hoods, slot hoods and local captures for tanks, process stations, and load/unload points with ergonomic access.
Inspection doors, drip legs, drains, and cleanouts located for maintenance—without compromising containment or airflow.
Hangers, guides, thermal expansion joints, and seismic/ wind bracing as required; interface platforms and ladders for safe access.
Leak checks, spark/holiday testing on dielectric liners, airflow balancing and readings, and close-out documentation with as-builts.
FRP and thermoplastic systems tailored to the chemical profile, temperature, and duty cycle of your process.
Permits, line breaks, rigging plans, and shift work that keep production safe and schedules intact.
Balancing data, QA records, and as-builts packaged clearly for maintenance and regulatory needs.
