Sodium Flame Platform

Inspect high-

efficiency filters.

We inspect each

high-efficiency

filter with partition

via a sodium

flame platform

before delivery.

In the sodium flame

platform made in

accordance with the

national standard

GB6165-85 Methods

for Testing the

Performance of High

Efficiency Particulate

Air Filter -Penetration

and Resistance, the

aerosol is sodium

chloride solution.

Characteristic light

with a length of

about 589 nm is

sent out through

hydrogen flame

excitation to sodium

atoms at a high

temperature and

transforms into a 

current value via a

photoelectric conwerter,

thus measuring the

initial efficiency of

each filter.

General Ventilation Filter Test Bed

Test general

ventilation filters.

We carry out

sampling inspection

on our general

ventilation filters

with this equipment

according to GB/T

2828 Sampling

Inspection by

Counting.

General ventilation

test bed designed

and made in

accordance with

the European

Standard EN779

generates test

aerosol with a

Laskin nozzle,and

takes samples

from the upper

and downstream

of the measuied

filter through a

laser particle

counter,thus

testing the full

efficiency of the

filter.

MPPS Inspection Bed

Test HEPA filters.

We test all the

partition-free

high-efficiency

filters of different specifications and

models with this

equipment before

packing.

MPPS test bed is

introduced abroad

and adopts the main

HEPA filter test

method in the word-

counting and

scanning method.

The test dust source

is dispersed droplets

generated with a

Laskin nozzle. It

scans and tests the

whole filter outlet

with a large-flow

laser particle

counter. The

counter shall test

the number and

particle size of dust

at each point.

performance of

chemical filters
