The Labculture blower system is designed for high performance operation, maximum energy efficiency and minimal maintenance.

• Ambient air is pulled through the front grille to prevent contamination of the work surface and work product. The inflow does not mix with the clean air within the cabinet work zone. Inflow air travels through a return path toward the common air plenum (blower plenum) at the top of the cabinet.
• Ambient air is taken in through a prefilter at the top of the cabinet, and passes through the downflow ULPA filter, entering the work zone as laminar flow. The uniform, non-turbulent air stream protects against cross contamination within and throughout the work area.
• Near the work surface, the downflow air stream splits with a portion moving toward the front air grille, and the remainder moving to the rear air grille. A small portion of the ULPA filtered downflow enters the intake perforations at the side capture zones (small blue arrows). The uniform, non-turbulent air stream protects against cross contamination within and throughout the work area.
• Near the work surface, the downflow air stream splits with a portion moving toward the front air grille, and the remainder moving to the rear air grille. A small portion of the ULPA filtered downflow enters the intake perforations at the side capture zones at a higher velocity (small blue arrows).
• A combination of inflow and downflow air streams forms an air barrier that prevents contaminated room air from entering the work zone, and prevents work surface emissions from escaping the work zone. The downflow combined with the inflow air enters the common air plenum.
• All air in the common plenum is HEPA-filtered and exhausted via a dedicated ducting system to the external environment.
  

• Esco cabinets use German made ebm-papst® permanently lubricated, centrifugal motor/ blowers with external rotor designs.
• Integrated blades norrow the profile and eliminate the need for a motor shaft.
• Motors are selected for energy efficiency, compact design, and flat profile. The completely integrated assembly optimizes motor cooling.
• All rotating parts are unitized and balanced for smooth, quiet, vibration-free operation.
