Product Q&A
Q:How to select suitable ventilation equipment for industrial workshops/factories?
A:
Focus on core operational requirements and four pivotal factors: 1. Calculate hourly air change volume (3-10 times/hr for standard, 10-20 times/hr for severe pollution). 2. Identify pollutant types (dust, oil, gases) to choose appropriate models. 3. Consider operating conditions like temperature and humidity. 4. Ensure compliance with local environmental and safety regulations. Contact customer service with specific parameters for a tailored plan.
Q:Do industrial ventilation equipment require installation by professional engineering teams? What is the installation process?
A:
Yes, installation must be handled by professional engineering teams with appropriate qualifications to avoid hazards. The standardized process includes: On-site survey, Pipeline design, Equipment positioning, Pipeline laying and sealing, Electrical wiring (explosion-proof/regular), Commissioning and operation, Environmental protection testing compliance, and Acceptance and handover, with technical personnel overseeing the entire process.
Q:What safety precautions should be taken during the daily use of industrial ventilation equipment?
A:
Pre-startup: Check fan, motor, pipeline, and filter for abnormalities; verify explosion-proof sealing and grounding. During-operation: Monitor air volume, pressure, noise, and temperature; stop immediately if anomalies occur. Personnel protection: Wear protective gear and avoid disassembling parts or approaching rotating components. Emergency handling: Turn off power, initiate emergency protocols, and evacuate personnel during power outages, fires, or gas leaks.
Q:What are the differences in maintenance priorities of ventilation equipment for different industrial scenarios?
A:
Welding workshops: Prioritize cleaning dust removal filter bags and inspecting spark arrestors. Chemical workshops: Emphasize anti-corrosion inspection and replacing waste gas treatment filter elements. Woodworking workshops: Focus on clearing wood chip accumulations to prevent clogging and fire risks, and check fan impellers for wear.
Q:What are the minimum order quantity and payment terms?
A:
The Minimum Order Quantity (MOQ) is 100 pieces. Accepted payment terms include LC, T/T, D/P, PayPal, Western Union, and Small-amount payment.
