RUWAC Ruwac’s FRV1400 includes an explosion-proof TEFC motor alongside a multi-stage centrifugal, high per-formance turbine and relief valve rated for 24/7 opera-tion. This vacuum’s “Bullet-proof” modular housing is fully grounded and made from a durable carbon im-pregnated, compression cast composite backed by a lifetime guarantee. Each FRV1400 vacuum features a foot-actu-ated dustpan for dustless clean-up and Ruwac’s industry-lead-ing MicroClean filtration. Connecting your FRV1400 to the HEC-XLT-EX will prevent fine dust from prematurely clogging your vacuum filter. The pre-separation system features Ruwac’s 12-inch high-efficiency cyclone and collects up to 97 per cent of fines prior to reaching the filter, reducing downtime and costly filter replacements in the process. www.lattaequipment.com ALLIED BLOWER For wood processing facilities demanding larger system capa-bilities, Allied Blower & Sheet Metal has successfully certified a line of Back Blast Dampers (BBD’s) that reach sizes up to 50 inches (1270 milli-metre) in diameter. The BBD can resist a vented dust collec-tor explosion reach-ing a Pred of 5 psi (0.35 bar) for dusts with a Kst of up to 200 bar-m/sec. This range provides safe operation for a large range of deflagrable dusts used in industry. When comparing a passive mechanical system or an active chemical suppres-sion system, the mechanical systems are perceived to have less maintenance costs due to simplicity in function, design, train-ing requirements, and the low frequency of inspections. With a mechanical BBD, mill staff do not need specialized training or tools when inspecting and keeping maintenance records for NFPA compliance. This results in more up-time, allowing for more production. Allied BBDs are built in Canada and designed for easy installation, inspection, and maintenance. The instru-mentation meets North American standards to easily integrate into a plant or mill PLC system and is available in Class 2 Div 2. A combination of Allied BDD and Allied’s NFPA certified rotary feeders can provide NFPA compliant passive isolation for large sized systems. www.alliedblower.com Canadian BIOMASS 27
