4.3. HEPA Filter Installation

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 1.5.1.

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

Warning!

Make certain power is disconnected from the oven before

removing or replacing the HEPA filter. Observe all applicable

safety procedures.

Caution!

The HEPA filter is fragile and care must be taken to avoid

damage during installation. If a filter unit is dropped, whether in

the carton or not, examine it carefully for damage.

Caution!

The HEPA filter must be installed so that unfiltered air cannot

leak past the unit.

Refer to installation instructions provided by filter manufacturer

for additional details..
