Hendee's Family of Industrial Protection Products

Railcar Filters

Hendee Enterprises developed their line of railcar filters in direct response to customers who used pneumatic unloading and were experiencing contamination during the unloading process.The filter can be used for shipping and unloading in combination with seals.

Hendee received an EQ (excellence in quality) award for development of these products as part of a quality program with a major resin manufacturer.
