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.

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 Isocide™ 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.

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

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 a sufficient number of air changes within the enclosed area of the straddle unit in order to maintain cleanliness.
