Laminar Flow Straddle Units
Esco Enterprise Laminar Flow Straddle Units are designed for the protection of large-scale industrial processes which typically require multiple units connected in an assembly line configuration. These straddle units eliminate the operating costs associated with a full-sized ISO Class 3 or 4 cleanroom as it can easily be placed inside an ISO Class 8 area to provide an ultra-clean environment for the main process.
Esco laminar flow clean benches are the premium selection for the discerning purchaser, offering a combination of value, high quality construction, low operating noise levels, and a wide product range to suit all budgets, from the industry leader.
Key Benefits:
Low noise
Reduced vibration
Energy Efficient
Disposable prefilter
Quiet, reliable, permanently lubricated direct drive centrifugal blowers
Long-life HEPA filter for supply airflow
Sterile work zone environment created for optimum product protection
Available in single, double, 1.2 and 1.8 meter (4’ and 6’) models
Multiple units may be connected for production line applications
Units are floor mounted with stainless steel work surfaces isolated from the main frame to reduce vibration
APPLICATIONS
Cleanrooms, electronics assembly, semiconductors, pharmaceutical, aerospace, and medical devices industries
Mycology and food microbiology
Plant and mammalian cell culture
Clinical pharmacy and hospital use
Eliminates vibration (work top good for weighing processes)
Non-biohazardous materials

During operation, room air is drawn through the top of the straddle unit via a washable polyurethane prefilter with 20% arrestance, trapping larger particles and increasing the life of the main filter
The air is then forced evenly through the HEPA filter with >99.999% efficiency, resulting in a unidirectional stream of clean air projected vertically over the internal work zone. All airborne contaminants are flushed and diluted, resulting in a particulate-free work environment
The purified air then leaves the storage area across the entire open front of the straddle unit
A nominal filter face velocity of 0.45 m/s (90 fpm) ensures that there is a sufficient number of air changes within the enclosed area of the straddle unit in order to maintain cleanliness
