BIO-ASSAY FLYING INSECT WIND TUNNELS
Sigma Scientific LLC manufactures standard & custom sized bio-assay wind-tunnels for any application.
Features
-
All of Sigma Scientific’s wind-tunnels have one flanged end where the blower draws the air in through the tunnel.
-
Both ends of the wind tunnel are covered with diffusing and filtering media, that are placed and compressed using a series of bolts.
-
The air-in side has several layers of activated charcoal-impregnated fiber, which when compressed serves two purposes:
-
As an air diffuser to develop high back-pressure on one side and produce a uniform / laminar flow through the media as the air passes to the low pressure side.
-
As a hydrocarbon filter to remove ambient VOC’s from the bioassay environment.
-
These wind-tunnels can have any number of access ports or doors and are able to be completely disassembled for alternating the configuration.
-
Both sliding access doors open to nearly half the length of the tunnel on both sides allowing maximum access and easy interior cleaning.
-
All of Sigma Scientific’s tunnels use a remotely connected high speed AC or DC blower motor which can cover wind velocities from 10 to 150 cm/sec. Higher velocities are available.
-
The motor is connected to the tunnel via a flexible aluminum duct which minimizes noise from the blower and isolates vibrations.
-
All Sigma Scientific tunnels come equipped with variable dampers allowing precise wind control.
Optionst
Additional side door access ports are available and cost $200 per door and can be placed anywhere on the tunnel. Additional accessories, ducting & custom options are available – Call for pricing.
