How it works
Robotic duct cleaning, step by step
Isolation-room exhausts and supply ducts are cleaned through existing openings only. Our robot and rotary-brush tooling reach the riser; our crew handles the rest. Pick a side of the system to see the sequence.

Featured project
21 negative-pressure isolation rooms. Five shutdown windows.
At Hospital Shah Alam we cleaned and sanitised the supply and exhaust systems of 21 isolation rooms across NICU, ICU, CCU and seven wards — each handed back inside its ward shutdown window, with a complete photo, video and robot-camera record.

Measured, not assumed
Clean air, held to the code
- <500CFU/m³
- Airborne bacteria limit under the DOSH ICOP-IAQ — the benchmark our IAQ assessments test against.
- ≤1,000ppm
- Target CO₂ level for occupied spaces — a simple, telling sign of adequate ventilation.
- 23–26°C
- Recommended indoor temperature band, held alongside 40–70% relative humidity.
- 12months
- Recommended interval for IAQ assessment and HVAC hygiene inspection in healthcare.
