Frits
The frits are designed for maximum flow rate. Microfil frits will allow flow rates up
to 50% higher than those obtained with glass frits. Their specific manufacturing
process annihilates the stainless characteristics of the stainless steel material. The
frits are therefore susceptible to oxidizing with time and will gradually develop a
darker brown color. When the aspect is no longer satisfactory, the frits should be
replaced (see "Product Ordering Information" section). The exposure to oxidizing/
corroding agents such as bleach will accelerate this phenomenon.
