Hi, We have refurbished blowers. Cleaned them, changed bearings, capacitor. These parts are standard parts, you will find them in "any" hardware store and Radio Shack type dealers.

pls share the photo with all. I would like to formulate a pie-chart on motor revolution

I think the problem is going to be the cooling zone location. All of the heat zones are built the same, but the cooling zone can not be moved easily.

Check your exhaust points and cooling zones. Cooling zones should have filters that need to be cleaned and it is most probably where your problem comes from. In front(if you have two exhaust pipes) you might need a filter change as well.

As we have vitronics oven(SMR610A) made in dec,1997,which has 5 heating zones and 2 cooling zones. For Lead free soldering what should be our baseline for low/medium boards.we have gathered profiles from various paste manufacturers,however we don't k

You should clean your cooling zones.

I believe this is a MELF, correct? If so, it could be your pad design. Most use a "horse shoe" style that seems to work well. Another thing to look at is your cooling zones. I've seen these parts remain liquidous into the cooling zone where they

You may not be getting enough exhaust pull, so the cooling modules over temp. Try swapping blower motors to isolate that before buying one. STANDARD AIR OPERATION: - Load-end: 150 cfm (255 m3/hr) at the 4� (102 mm) stack (minimum requirement) - Unlo

With high volume production, this can happen. The flux is vaporizing in the heating zones, and is condensing in the cooling zones. Depending on the machine, cooling can act differently on different machines. Less cooling may reduce this problem.

I am seeing a problem of flux droping on the PCBA during reflow. This is a pb free process and I am using KOKI pb free paste with 8 zone (and some 9 zone) reflow ovens. Line throughput is about 10,000 boards/24 hours. I suspect that the exhaust is no
