Lawrence Factor Hyper Pure Filter Stacks

I have up for sale a Lawrence Factor Hyper Pure Filter Stack. The stacks will process 40,000 cu. ft. of Modified E air based on input of Grade E at 70 degrees. They are in excellent condition and ready to use after installation of new filters. Lawrence Factor has one of the best prices for filters directly from their website. 1800.00 for the stacks plus shipping or pick up in Middle TN with possible delivery to FL panhandle just before Thanksgiving. Please PM or email with any questions. I'll be at DEMA from the 19th till the 25th but will check emails once a day or call 931-626-6416.
