Q1: What’s the main advantage of your heater fan kits compared to buying components separately?
A: We provide integrated, compatible solutions. Our kits, like the one supplied to Iran, include precisely matched components(gas blower fan, cross flow fan, controls). This eliminates compatibility risks, simplifies your supply chain, and ensures optimal system performance and safety as a one-stop shop.

Q2: Can you customize the fans or the entire kit for our specific heater model or project?
A: Absolutely. Customization is our core strength. We can adjust specifications (size, voltage, speed, airflow/pressure), modify designs for OEM, and tailor complete kits (including PCB logic, thermostat set points) for projects. We serve as your true single-source solution partner.

Q3: Are your products certified for international markets, such as the EU or North America?
A: Yes. Our production is certified to ISO9001 & ISO14001 standards. Key components and finished fans can be manufactured to comply with CE, UL/ETL, RoHS and other required directives, supporting your market access.

Q4: What are your key quality control measures?
A: We implement strict QC throughout the process: from raw material inspection, in-process checks during assembly and balancing,to final performance testing (airflow, noise, pressure, electrical safety) in our dedicated testing lab. This ensures every unit meets specification.

Q5: What is your typical lead time and what support do you offer after purchase?
A: For standard models, lead time is 15-30 days. We offer 24/7 technical support, comprehensive documentation, and a warranty of up to 18 months. For urgent replacement needs, we provide an expedited channel.
