Quest-Air Technology Phils., Inc.

The Company’s major milestones:

- Business office and shop was set-up in a 200 sq. meter rented motorpool in Mandaluyong City.
- Completed TDK’s first manufacturing line in the Philippines. The 2,000 sq. meter production floor was a combination of Class 10k and Class 100k Cleanroom.

- Built Texwipe’s Class 100 laundry room. The first Class 100 cleanroom in the Philippines.

- Transferred to Muntinlupa City and acquired the state-of-the-art duct fabrication machineries

- Engaged in projects outside the semiconductor and electronics industry that includes Philip Morris Mfg. facility (Batangas), International School (BGC) and NAIA Terminal 3 which Dai-Dan Ltd. of Japan assigned QAT to fabricate and install the buildings airconditioning ductworks.

- Constructed the company’s own office and fabrication facility in a 2,600 sq. meter lot in Biñan, Laguna.

- Ventured into commercial projects in Cebu – Buildcomm Center and Oakridge IT Center 2.
- KCC Group continued to challenge QAT’s capabilities and was given a project that would involve the company in a different feat. . . the 3.3 MW Biogas power plant and a 7 MW Biomass power plant in Southern Cotabato.
