Astro Pak offers coast-to-coast Cleanroom Services facilities, featuring ISO 14644-1 certified Class 5, 6, and 7 cleanrooms and labs of various sizes and capabilities. These highly controlled environments support processes such as ultrasonic cleaning, pressure and cold shock testing, clean assembly, vacuum-sealed packaging, and cleanliness verification for particle count, TFS, and NVR. Additionally, our Cleanroom Services locations maintain AS9100 certified Quality Management Systems.
Downey, CA
Our California Cleanroom houses three large ultrasonic cleaning units (8’L x 3’W x 3’H). One of the highlights of this facility is the a 21,222 cubic ft Large Component Cleanroom that features a 26’x15’ high-speed roll up door, 18′ ceilings, 2,500 psi high pressure spray system and two-ton overhead bridge crane to accommodate large hardware.
Titusville, FL
Located just outside the Kennedy Space Center, Astro Pak’s 38,000 sq. ft. Space Coast facility houses three L-Shaped Tanks (22’L x 3’W x 4’H by 3’L x 2’W x 4’H). The highlight of this facility is the 15’x15’ enclosed tower (70’ vertical) which enables the processing of convoluted hoses up to 60’ in length indoors in a vertical orientation.
methods
High-Pressure Spray Cleaning
This technique employs the kinetic energy of a water jet to "blast" particles and soils from a surface. It is often used alongside detergents or surfactants, which chemically loosen or dissolve the soils, enabling the water jet to more effectively remove contaminants. The method's adaptability, through adjustable water pressure, nozzle size, and spray pattern, allows for customization to suit different materials and soil compositions.
Ultrasonic Cleaning
Ultrasonic cleaning uses high-frequency sound waves to induce cavitation, agitating the cleaning solution and dislodging particles. It excels at precision cleaning complex parts with threads, rough surfaces, and blind interior spots inaccessible by other methods. This technique typically utilizes aqueous, semi-aqueous, and solvent-based detergents to remove contaminants at virtually a microscopic level, with higher frequencies removing finer particles.
Flush Cleaning
This method is particularly useful for precision cleaning components with varying shapes and sizes for which high-pressure sprays are not useful. By generating a turbulent flow, cleaning fluids are flushed through the internal passages of tubes, pipes, and other intricate pathways. As the component rotates, the turbulent flow dislodges and flushes out contaminants from the interior surfaces.
Aqueous Cleaning
This water-based cleaning technique excels at removing various contaminants from parts that are water-compatible, allowing for extended dwell times in the cleaning solution. Deionized or reverse osmosis treated water is combined with detergents and surfactants. The result is an environmentally-friendly method that achieves the desired level of cleanliness on the parts.
Wipe Cleaning
This method employs special lint-free and particle-free wipes or swabs, typically moistened with solvents or deionized water, to manually clean delicate surfaces that cannot tolerate more aggressive cleaning techniques. The use of these specialized wipes ensures that no additional particles are introduced during the cleaning process.
Solvent Cleaning
Solvent cleaning is especially effective for parts with complex configurations and specific soil compositions. This method leverages the chemical properties of the solvent to eliminate contaminants from the part. In some cases, solvent cleaning is used in conjunction with ultrasonic cleaning for enhanced results.
accreditations
Astro Pak has cleaned hardware and components for almost every cleanliness critical industry and application since 1959. Our studies have shown that the chrome to iron ratios achieved by our Ultra Pass® passivation far exceeds ASME BPE recommended minimums and meets or exceeds the requirements of many industries including pharmaceutical, biotechnology, space and semiconductor. Some of the world’s most prestigious institutions including JPL, Lawrence Livermore National Laboratory, MIT, and Cal-Tech have sought guidance and consultation from our subject matter experts. For cleanliness critical components our Cleanroom Services locations are ITAR certified and feature ISO 14644-1 certified Class 5, 6, or 7 cleanrooms and labs of varying sizes and capabilities. We also house an extensive library of approved procedures and meet the standards and specifications set forth by both industry regulatory bodies and private organizations. Our Cleanroom Services locations maintain AS9100 certified Quality Management Systems.

Frequently Asked Questions
ISO 6 or Class 1,000 is a cleanroom classification that measures the cleanliness level of a cleanroom, which is measured by the maximum limit of particle volume and size that is allowed per cubic meter of air inside a cleanroom. A common misunderstanding is that a component needs to be cleaned to a level that allows its use within a specific class of cleanroom. Instead, components are cleaned to meet a measured limit of contaminants, such as the Particle Count and/or Non-Volatile Residue (NVR), which are typically supplied by the customer or defined by an industry standard.
