Laminar Flow Straddle Units

Laminar Flow Straddle Units

Esco Enterprise™ Laminar Flow Straddle Unit, Single/Double (ESUS/D) is the leading solution for industrial process protection. It is also suitable for large-scale industrial processes which typically require multiple units to be connected in an assembly line configuration.

Maintained with a vertical laminar flow of air, the unit is available in either single or double-sided models. In comparison to horizontal laminar flow designs, the vertical laminar airflow of the unit generates less turbulence around large pieces of equipment.

As a cost-saving boost to cleanrooms, the straddle unit provides an ultra-clean environment directly at the process level and may easily be placed in an ISO Class 7 cleanroom. This allows the elimination of initial and operating costs which are associated with full-sized ISO Class 5 or better cleanrooms.

Esco Pharma provides the highest quality of construction and manufactures a wide range of equipment for the most demanding cleanroom applications.

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
Applications benefiting from the isolated work surface frame design which virtually eliminates vibration (good for weighing processes)
Handling of non-biohazardous materials where operator protection is not required

Features

Low noise
Quiet and smooth operation with reliable permanently lubricated direct drive centrifugal blowers
Effective filtration system
Long-life HEPA filter/s are equipped for the supply airflow for sterile/aseptic work zone environment created for optimum product protection. Also, an additional disposable pre-filter on all models traps large particles in the inflow air prior to reaching the main filter, protecting it against damage and prolonging its life.
Easy-to-clean optional worktop
The optional worktop surface is constructed of stainless steel, making the work zone easy to clean.
External IsocideTM antimicrobial powder coating
Esco antimicrobial coating on all painted surfaces minimizes contamination.
Single/Dual and 4’/6’ configurations
Available in single, double, 1.2 (4’) and 1.8 meter (6’) models
Connectable units for large-scale processes
Multiple units may be connected for production line applications.
Reduced vibration
Units are floor-mounted with an optional stainless steel worktop isolated from the mainframe to reduce vibration.
Excellent illumination
Built-in warm white, electronically ballasted, 5000k lighting provides excellent illumination of the work zone and reduces operator fatigue.
Enhanced operator comfort
Transparent polycarbonate side panels enhance visibility and create a more comfortable work environment for the operator as opposed to conventional stainless steel or painted steel sides.
Guaranteed cleanroom compatibility
All straddle unit components are cleanroom compatible.

Principle

During operation, room air is drawn through the top of the straddle unit via a disposable 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 a typical efficiency of >99.999% at 0.3 micron particles, 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 sufficient number of air changes within the enclosed area of the straddle unit in order to maintain cleanliness.
