Ahlstrom Grade 55 Filter Paper is a fast-filtering paper for use in triaxial shear strength, flexible-wall permeability, and other soil testing procedures to prevent migration of soil fines from samples and blockage of pores in applications where porous stones are used. It is equivalent to Whatman Grade 54 as recommended in a number of ASTM and AASHTO soil test methods to prevent migration of soil fines and blockage of pores in porous stones.

This high-purity paper features high resistance to strong acid and alkali solutions, increased wet strength, and a tough, smooth surface free of loose fibers. It has 15µm retention and a filtration speed of 220ml/min. The circular pre-cut filters are available in a package of 100.

Q: Will this work with fan-forced heaters?

I'm very satisfied with this product. It was exactly what I wanted in my travel trailer, for a lot more accurate heating. Now I can pinpoint it to exactly the temperature I want, instead of guessing, sliding the conventional thermostat back and forth. Will for sure save on propane too! Nice back light when adjusting the temperature, making it easy to see even at night.
