Air Preheater Gear Boxes

Penn Machine has over the years earned the trust of customers worldwide and now, in cooperation with Air Preheater Co. is offering this same commitment to quality and service for your Air Preheater gearbox. Immediate parts availability, drop in replacement gearboxes, and rebuilds to OEM specifications top the list of what Penn Machine has to offer to you, the customer.

While you may or may not realize it, the OEM gearing in your gearbox utilizes the Falk Universal Tooth Form. Your gearbox is engineered to perform at peak efficiency using this proprietary gearing. Non-OEM gears can not be used in conjunction with OEM gearing and, perhaps most importantly, are rarely immediately available in the event you experience an emergency breakdown.

Penn Machine stocks for immediate delivery ALL of the components for your Air Preheater gearbox, including gears, shafts, bearings, seals, and even replacement housings. When you take into account the increased costs incurred everyday your Air Preheater is down, can you really afford not to go with OEM replacement parts? We can offer:
  • Air Preheater Company authorized replacements for 3AP, 4AP, 5AP, 7AP and 8AP Falk manufactured gearboxes.
  • Rebuilds to OEM specifications utilizing Falk Universal Tooth Form Gears and Pinions. Parts are discounted when Penn Machine performs the service.
  • Complete spare parts inventory for 3AP, 4AP, 5AP and 7AP gearboxes means immediate availability and less down time.

For your convienence, we have included parts guides, clutch rotation guide links to the following Air Preheater models:
