I'm reaching out to gather some info about flame arrestors suitable for our 20" fluidizing suction air pipe. We need to ensure the product meets our safety and efficiency standards, so it would be great to learn more about the specifications, materials used, and any certifications you might have for your flame arrestors. Additionally, please share details on pricing, lead times, and bulk order discounts if available. If there are different models or options you offer, I'd love to compare those as well. Looking forward to your response so we can continue this discussion!
