Esco Cleanroom Equipment

Since 1978, Esco has been a pioneer in the development of cleanroom technology. Today, Esco operates 100,000 square feet of state-of-the-art cleanroom equipment manufacturing floor space with more than 400 employees. Our vertically integrated capabilities include CNC sheet metal fabrication, stainless steel fabrication, electro-mechanical assembly, and complete performance testing of all products before shipment.

Integrated sourcing from the world’s leading component suppliers including Swedish Camfil-Farr® HEPA/ULPA filters, German ebm-papst blowers and fans, enable us to meet your Cleanroom Equipment requirements at a competitive price with rapid delivery.

Cleanroom Air Showers

Air Showers are self contained chambers installed at entrances to cleanrooms and other controlled environments. They minimize particulate matter entering or exiting the clean space. Personnel and materials entering or exiting the controlled environment are "scrubbed" by high velocity HEPA-filtered air jets with velocities of 20-22m/s (4000-4300fpm). Contaminated air is then drawn through the base within the unit, filtered and recirculated.

Esco is a leader in air showers for demanding applications in the micro-electronics, semiconductors, pharmaceutical, spraypainting, lab animal research and food markets. Esco filed its first Air Shower patent in the 1980’s and since then has installed thousands of units in diverse markets worldwide. The present Esco Air Shower is a third-generation product and features a field-programmable microprocessor control that offers the maximum application flexibility of any unit on the market.

Cleanroom Applications: The greatest source of particulate contamination in a cleanroom is the operator. Air showers are installed between change areas and the cleanroom. The air shower enhances cleanroom operating protocol by serving as a reminder to all operators that they are entering a controlled environment. Personnel therefore develop the habit of gowning up properly before entering the air shower.

Pharmaceutical and Lab Animal Research Applications: Air showers keep pharmaceutical production and lab animal breeding areas clean and also minimize egress of hazardous substances and allergens from the controlled environment.

Key Benefits:

• Disposable prefilter
• SS air nozzles
• Energy Efficient
• Microprocessor controller
• High velocity shower jets
• Emergency stop buttons

Features:

• High velocity shower jets in excess of 20 m/s ensure efficient scrubbing action to remove particulate matter.
• Operating modes can be programmed in the field.
• Microprocessor controller supervises all functions.
• Mini-pleated HEPA filtration achieves > 99.999% typical efficiency at 0.3 micron particles.
• A disposable pre-filter with 85% arrestance extends the life of the main filter.
• An emergency stop button is mounted on both sides of the shower.
• Indicator lights mounted on both sides of the air shower exterior regulate traffic flow in and out of the cleanroom.
• Permanently lubricated direct drive centrifugal blowers are used in conjunction with stainless steel air nozzles.

Cleanroom Transfer Hatch

Controlling the ingress of particulate contamination into cleanrooms and other controlled environments is paramount in order to maintain the integrity of products and processess. Personnel traffic is the most important factor which must be controlled. Esco Pass Boxes and Transfer Hatches are a cost effective solution as they allow materials to be transferred into the controlled environment without actual personnel movement. They may also be used to protect the external environment from egress of contamination, for example, in biological safety laboratory applications.

Key Benefits:

• Cost effective
• Reliable mechanical interlock
• Pharmaceutical-grade SS
• Safety glass
• Single piece of SS interior

Features:

• Mechanical interlock is reliable, maintenance-free, fail safe and maintains cleanroom integrity by preventing both doors from being opened at the same time. The interlock design has been life-tested to 10,000 cycles to guarantee long service life.
• All Esco products are manufactured for the most demanding controlled environment applications.
• All components are designed for maximum chemical resistance and enhanced durability for a long service life.
• The main body of the pass box is constructed of pharmaceutical-grade stainless steel.
• The internal side walls of the pass box are constructed from a single piece of stainless steel, with coved corners for easy cleaning.
• Transparent 10 mm (0.3”) tempered glass doors provide visibility into the interior. Frameless construction is easy to clean with no joints in which contaminants may accumulate.
• Durable feather edge rubber gasketed door seals maintain cleanroom integrity and are easy to clean.
• Pass box hardware has been custom designed for reliable service featuring large, durable hinges, and ergonomic handles.
• One stainless steel mounting flange is included.
• Extended 3 year warranty.
