5.3. HEPA Filter Handling, Installation and Burn-off

Not all LCC/LCD ovens come equipped with a HEPA filter. This HEPA filter
installation section applies only to ovens designed for ISO Class 5 (Class 100) use,
which are equipped with a HEPA filter. For a complete explanation of model
numbers, refer to Section 2.1. Two different types of filters are typically used.
While both filters are high-temperature filters in that they are designed for use in
thermal processing equipment, the "standard" HEPA filter is rated to 260°C (
500°F) while the "high-temperature" HEPA filter is rated to 350°C (662°F).
Each LCC/LCD oven uses one of two types of HEPA filters,
depending on the oven's maximum temperature. Ovens that can
be heated to 260°C (500°F) use the Standard HEPA filter. Ovens
that can be heated to 350°C (662°F) use the High-Temperature
HEPA filter.

However, customers requiring a higher ramp rate while
operating equipment below 260°C (500°F) may still choose to use
the high-temperature HEPA filter:
• Standard HEPA filter ramp rate: 1.25°C (2.25°F)/minute
• High-Temperature HEPA filter ramp rate: 5°C (9°F)/minute
