Welcome to Weifang Epp Environmental Protection Equipment Co.,Ltd.!
  • Do you offer custom dust collectors? Can you design one based on our specific application requirements?

    Yes, we focus on providing customized solutions, not standardized products. During the initial phase of the collaboration, our engineers will conduct a three-step process to precisely match your needs:

    Operating Conditions Survey: This will collect key parameters such as flue gas temperature, dust concentration, air volume, environmental emission standards (e.g., local ≤10mg/m³ or ultra-low emissions ≤5mg/m³), and installation site dimensions.

    Scheme Design: Based on this survey data, we will select the appropriate filter media (e.g., PPS for medium-temperature, sulfur-containing flue gas, PTFE for high-temperature, highly corrosive environments), determine equipment size, cleaning method (pulse jet/mechanical vibration), and auxiliary systems (e.g., preheater, ash discharge valve).

    Scheme Confirmation: We will provide detailed equipment drawings, technical specifications, and a quotation, and discuss adjustments with you to ensure the solution fully meets your actual operating requirements.


  • I'm not sure which model of bag filter to choose. Can you provide selection guidance?

    Absolutely. Our team of professional engineers will assist you throughout the entire model selection process. No specialized knowledge is required; simply provide basic information and we'll provide accurate model recommendations. We'll also discuss solutions and answer any questions through online meetings, ensuring your selection is tailored to your needs.




  • How do I get a quote for a bag filter? What information do I need to provide?

    The quote request process is simple and transparent, with a formal quotation issued in as little as 1-3 business days. The steps are as follows:

    Submit a quote request: You can submit a request in two ways: ① Fill out the "Quote Request" form on the website; ② Contact our customer service or your dedicated account manager directly to explain your purchase requirements.

    Supplement Key Information: Our team will contact you within one business day to confirm the key information required for a quote (consistent with the selected model, including air volume, flue gas temperature, dust type, environmental standards, equipment quantity, and the need for spare parts). If you have already selected the model, you can directly provide the selection report number to expedite the quote process.

    Issuing a Formal Quote: Our engineers will calculate the cost based on the confirmed information and issue a formal quotation in English. This information includes the equipment model, specifications, unit price, total amount, payment method, production cycle, warranty period, etc., and will be sent to you via email.

    Communicate and Adjust the Quote: If you have any questions about the quote or require configuration adjustments (such as adding spare parts), please contact us at any time and we will update the quote.


  • There is no on-site installation service after the equipment arrives. How can we ensure that we can install it correctly?

    We offer remote pre-installation consultations: One to two weeks before installation, our engineers will meet with your installation team via video conference to confirm the availability of all installation tools (such as lifting equipment and wrench specifications) and to discuss potential pitfalls.

    Real-time installation guidance: If you encounter any questions during installation, you can contact our engineers via our 24-hour after-sales hotline or video calls (such as Zoom and Teams). They will provide hands-on guidance and resolve any issues through screen sharing and real-time annotation of drawings.


  • If a device malfunctions during operation, what is your after-sales response process? How long does it take to provide a solution?

    If you encounter any equipment problems, we provide professional technical support and provide comprehensive guidance on problem resolution.

    Response Time Guarantee: On business days, we will contact you within 24 hours to collect fault information (such as fault symptoms, operating parameters, and photos/videos of the abnormal area). Simple issues will be resolved within the same day; complex issues (such as component failure) will be accompanied by a diagnostic report and solution within 1-2 business days.

    Problem-Solving Support: If parameter adjustments are required, we provide remote guidance. If component replacement is required, we will immediately coordinate shipment from our overseas spare parts center and provide video tutorials on component replacement to ensure your team can perform the replacement themselves.
