I hope this message finds you well. I'm reaching out to request a detailed quotation for the air quality detection system we discussed earlier. Specifically, I'm interested in a particular model that's designed to work seamlessly within duct systems. We're looking to purchase a total of six units, so please include any bulk pricing or discounts you might offer, along with your standard lead times for delivery. Additionally, it would be helpful if you could provide information on any warranty or after-sales support available for this model. If there are any relevant specifications or documentation that would assist us in assessing the product, please include those as well. Looking forward to your prompt response so we can move forward with our procurement process.
