iso ul New UL UniFlow Fume Hoods
UniFlow HDPE Acid Digestion Fume Hoods

UniFlow Acid Digestion fume hoods feature a one piece fume chamber with integral reinforced work surface, and baffles constructed of HDPE. Digestion hoods come in 48”, 60”, 72” & 96” widths & feature a dedicated wash down & exhaust system.

UniFlow Superstructure constructed of HDPE exclusive unitized dual wall construction for superior chemical resistance (NO RUST), strength, and durability. Vent outlet is integral to superstructure and is available in HDPE lined hoods.
 
Fume Chamber and baffle are constructed of type 1 PVC liner with 24" or 30" interior depth. The one piece liner is engineered to resist reactions from corrosive chemicals that don't require high temperatures.
 
HDPE Work Surface is welded integral to the fume hood superstructure and dished to contain spillage and includes welded in rear drain trough. If a sink is required HDPE would allow the sink to be welded in. color: white
 
Access Panel removable to access ducting connections and electrical services from a single point electrical box, 115V/60Hz AC operation. Full 28” viewing height for ease of access and viewing tall apparatus setup. Sash is 3/16 thick tempered safety glass, vertical moving for efficient air flow and ease of movement
 
Sash to be counterbalanced connected with coated stainless steel cables, 3/16" unbreakable polycarbonate with chemical resistant non-metallic PVC framing track and aerodynamic sash lift.
 
4” and 30” Interior depths available to meet your specs.
 
Wash Down System hood is equipped with spray nozzles, piping, valve and rear drain trough for rinsing wash down after usage.

SASH MANAGEMENT 1-2-3

1. Cut energy costs up to 50%. For improved lab efficiency air flow monitors check the fume hood face velocity & help to insure that the proper amount of room air changes per hour are maintained. The sash stop is designed for user protection and cfm reduction, allowing the sash to
open to a maximum position of half open. With an average utility rate of $7.00 per cfm a typical annual savings on a 4' fume hood would be $2705.00 on a 6' fume hood $4067.00.

2. Sash should only set to full open position for the set up of tall apparatus. Personal safety protection should be worn as recommended by the Lab Safety Officer.

3. When the fume hood is not in use return the sash to the closed position.

Fume Hood Face Velocity

The recommended face velocity for efficiency
& safety is 80-100 fpm. Lower face velocity may compromise user safety.

Sash in full open position should be for setup of
apparatus & maintenance service only. If opening
is at 1/2 open at 100 fpm (feet per minute), face
velocity at full open would be approximately 50 fpm.
