In our newsletter/May 09   Helping out with Habitat for Humanity Kathy Stemen cutting boards for framing day at Habitat for Humanity in Delphos, Ohio.  Kathy not only represented Fiber Concepts, but was part of the Lima chapter of NAWIC, National Association of Women in Construction. Denny Stemen, right, of Fiber Concepts In other news, ramp up money and insulation credits are starting to help the industry. With lots of quotes going out for equipment for this new stimulus money, keep in mind the lead time needed to prepare your order.  Present time is 4 weeks out.       Archives: In our newsletter this month, we will give some basic information in helping you choose the right equipment that will not only meet your fiber and application needs of today, but room to grow for tomorrow.  There are two basic types of machines: through the blower machines and all fiber, airlock style machines.  Through the blower machines: Krendl’s 250A is a modification of their original 200 machine developed 50 years ago. The 200  was an industry workhorse for over 35 years. With the 250A’s design, they took the best of the 200 and enhanced it to perform even better. This is a cellulose only machine. The fiber travels through the agitators and then is propelled through the 309 blower. The machine is sold separately from the blower, so keep this in mind when ordering. All fiber, airlock machines: During my employment with Krendl in the 1980’s, the first all fiber machines were developed. Fiber is conditioned through the agitators, then drops into a stationary cylinder shaped airlock. There is an opening at top of the airlock for the fiber to drop into, an opening at the lower back that attaches to the blower, and an opening at the lower front where your hose attaches, to carry the fiber to your destination.The 6 veined paddles with rubber seals, rotate, moving the fiber while the blower pushes the fiber through it to your hose. The blowers come standard with the machines and push fibers from behind  the airlock to the hose, instead of going through the blower itself. Due to this design, cellulose, rock wool, fiberglass, and even sheep’s wool can blow through these units. Newer developments of these units is the slide-out airlock for reduced maintenance downtime, and larger hopper capacity.   1300 vs. 2300 machine: These two machines are very similar in many ways. They have the same hopper  (33 cu. ft.) capacity, drive motor, blowers, and agitators. The difference lies with the length of the airlock. The 1300 has a 12” (30.5cm) diameter x 12” (30.5cm) long airlock. The 2300 has a 12” (30.5cm) diameter x 16” (40.6cm) long  airlock, giving a greater production rating. As an example, production rates for cellulose in a 1300 are estimated at 2400 lbs./hr. and the 2300 estimates 3000 lbs./hr. However, with more fiber moving through the airlock the drive motor may work harder. That’s all for now. Will discuss applications in my next newsletter. Regards, Kathy and Denny Stemen                                                                          3/09
