A key issue with smaller air scrubbing units (often 2,000CFM per machine) are the constant hassles of replacing filters to avoid rapid performance drop-offs. In simple terms, most of these systems try to force too much “dirty” air through to little filter media causing performance to drop in some cases before a single shift is completed if there is sufficient dust being produced such as during heavy renovation and/or demolition work. The BlueSky Defender™ negative air machine is comprised of modular stacks which allow the air-to-cloth ratio to be optimized for each application by simply adding or removing filter stacks. This moves filter replacement intervals to an annual task, not a daily or weekly annoyance.

Yes, the Defender™ negative air system is specifically designed for hazardous applications, and comes standard with True HEPA (>99.97% @0.3microns). Common hazardous applications range from asbestos remediation, to lead abatement and Nuclear D&D. For the most hazardous and regulated dust types such as radiated dust applications, an optional secondary (police) True HEPA stage can be added, and onsite DOP testing of the complete system can be completed.

Airflow requirements depend on the capture method (room capture or point-source capture). For room capture, the key parameters to determine are the volume of the containment area and the desired air changes per hour (ACH). For point-source capture, the cross-sectional area, estimated distance from the dust/fume generation source, and general environment surrounding the capture point (windy outdoor location or controlled indoor area) are the key inputs. The BlueSky® technical team can assist further in determining the correct airflow and dust collector/negative air machine needed based on these parameters.

BlueSky® machines are all-electric, avoiding the maintenance hassle of combustion engines. This allows the BlueSky® Defender™negative air machines to be placed inside the containment using a forklift for continued operation with no need to connect ducting, or constantly refuel a diesel engine.
Power plugs are provided with each machine which can either be connected to facility power or to a generator, depending on what is available at the jobsite.

BlueSky® machines are electric-powered, have no diesel motors, and no hydraulics. Maintenance is simply replacing filters, which can be out-sourced with BlueSky® Turnkey service.  They are designed to be plug-and-play systems which do not have to be touched again after the initial setup, optimized for field work, temporary applications, and challenging project work.
