Specifications include, but are not limited to: This requirements description covers an electrically powered dust collection system of sufficient capacity to support a 5 axis router system, defined herein, dedicated to machining operations for carbon fiberreinforced plastic [CFRP] composite and similar materials. Explosion protection, meeting current industry regulations, shall be an element of the system design, along with replaceable filtration elements configured for optimum containment of carbon fiber residue. • Eight thousand [8,000] cubic feet per minute [CFM] minimum through a distributed interface with a CR Onsrud Model F144Q17 5-Axis QUBE Series 5 axis router of four [4] pick up duct collection points of eight [8] inch [nominal] diameter as shown in Figures 1 A and 1B. • System noise shall be below 78 db • Fourteen [14] replaceable filtration elements with a provision for periodic automated compressed air pulse cleaning during operation of the system. o Replacement access of the filers shall be from the dirty air side of the unit. o Filtration levels shall be sufficient under the projected dust particle environment from machining of carbon fiber, vinyl-ester, epoxy or plastic media tooling board to allow for an option of recirculation to the HVAC controlled environment of the facility shop vs. to the exterior in consideration of shop environmental control efficiency. o Filters shall be of an antistatic format. Clean air emissions value to be: < 0.5 mg/m3. o Targeted operational life of the filter set under rated conditions to be up to 20,000 hours. • Dual containers – 2 X 13 gallons - waste collection into separable containers • 460 VAC, 3 Phase, 60 Hz supply unless otherwise agreed to by the Customer. Control voltage shall be 24V. • Primary structure shall be of welded steel construction for frame, collector, fan mounting section and similar load bearing / containment structures segments. Corrosion protection shall be by chemical process surface treatment and / or paint suitable for either interior unconditioned space or external to the facility under an open shelter structure, i.e. roof but open sides. • Direct drive motor type fan, top mounted and include a noise reduction suppressor. Fan motor shall be UL rated and the assembly shall incorporate multiple sensors for overheat detection. • Passive provisions for decoupling of explosive flame and pressure in accordance with NFPA 69 requirements and guideline 94/9/EC [ATEX] or Underwriters Laboratories [UL] and NFPA equivalents. Ducting shall be reinforced in sections as required to meet the standards. Sensors shall be incorporated for wear and debris deposits to facilitate preventive maintenance monitoring. • Interface ducting and its installation between collector and router, separate from the reinforced ducting associated with the explosion protection provision, may included as a line item separate from the primary system.
