Astro Pak expands precision cleaning cleanrooms in CA

May 10, 2012 – Marketwire — Astro Pak Corporation opened its Class 100 and Class 1000 cleanrooms, recently renovated and expanded, in Downey, CA. The cleanrooms host contract precision cleaning for the semiconductor manufacturing, aerospace, and other industries. Astro Pak believes the California location to be the largest of its kind in the US.

The modernization began in early 2011, aiming to improve services and expand capacity. Astro Pak’s Chesapeake, VA cleanroom facility was completed in January 2012.

The Downey cleanrooms are situated on 3 acres, with more than 35,000sq.ft. for Class 5, 6, 100 and 1000 cleanrooms under ISO 14644-1. Astro-Pak is ISO 9100:2008 and AS9100 revision C certified, noted Ignacio Quiroz, production manager for the Downey facility.

The new large-component Class 6 cleanroom measures 40′ x 30′ x 18′ (height), and supports a 2,500 psi high-pressure spray system. A 4,000lb bridge crane will move heavy hardware and components.

The new high-volume component/hardware processing cleanroom houses a 1,500sq.ft. Class 100 space and 2,100sq.ft. Class 1000 space, supported by a modern 6,000sq.ft. preclean area. The preclean area includes 8 work stations, 4,000lb bridge cranes, 3 large Ultrasonic cleaning units (3′ x 3′ x 8′), and a high-purity, high-pressure spray system integrated into the area that houses additional immersion tanks.

A new safety containment pressure test room was built for pneumatic pressure testing, and a new hydrostatic pressure test stand was also designed. Pneumatic testing is performed up to 10,000 PSI and Hydrostatic testing up to 30,000 PSI.

From pre-commissioning and maintenance projects to planned shutdowns and emergency outages, Astro Pak has a proven track record of cleaning and passivating ultrapure water systems for semiconductor manufacturers and more.

Astro provides precision cleaning and passivation services in North America for the aerospace and defense, medical device, semiconductor, laser, biopharm and other markets. For more information, visit
