IST (Kresco) Paint Booth Exhaust Ductwork
IST (Kresco) equipment is often associated with abrasive blasting rooms, media handling and industrial surface preparation. When exhaust ductwork is part of a finishing or blast area, the layout has to account for capture points, fan access, dust loading, roof or wall discharge paths, make-up air and the maintenance space needed around connected equipment.

Air Path From Work Area to Discharge
Double D Mechanical reviews how air leaves the enclosure, where the fan or collector sits and how duct routing affects nearby production. Straight runs, elbows, transitions and penetrations should be planned with the work envelope and building structure in mind.
- Confirm the enclosure opening, plenum location and intended exhaust connection point.
- Review crane travel, fork truck aisles, mezzanines and overhead utilities.
- Identify roof, wall or exterior discharge constraints before fabrication.
Dust, Overspray and Service Reach
Blast and finishing exhaust systems need room for filter changes, cleanout, fan service and inspection. Access panels, collector doors, ladders, platforms and removable sections should not be boxed in by later trades or storage areas.
Replacement Air and Pressure Effects
Exhaust ductwork changes how the room pulls air from adjacent spaces. Make-up air, open doors, nearby booths and plant HVAC can all affect capture. Planning should consider whether operators will see drafts, poor visibility or pressure swings during production.
Field Details Before Layout
Useful site information includes equipment drawings, ceiling height, roof framing, exterior wall conditions, fan location options, existing duct sizes, electrical disconnect locations and photos from inside and outside the proposed route.
Frequently asked questions
What does IST (Kresco) exhaust ductwork planning involve?
It involves routing from the booth or blast enclosure to the fan, collector or discharge point while preserving airflow, clearances and maintenance access.
Can ductwork affect booth or blast room performance?
Yes. Long runs, sharp transitions, blocked intakes or poor replacement air can reduce capture and create unstable air movement in the work area.
What should be checked above the ceiling or roof?
Structural framing, roof slope, curbs, nearby stacks, drains, gas lines, electrical runs and safe access for future fan or duct service should be reviewed.
What should the plant have ready for a walkdown?
Have equipment drawings, planned workpiece dimensions, current duct information, roof photos, utility locations and notes on production hours or shutdown windows.
