Alpha Line Lab Business, a laboratory safety integrated management company.

This is the work requested by the Kkaebi Farm, which is the posting I will show you 

this time, and it is the replacement of the clean bench filter.

The airflow from the clean bench is discharged from the inside of the

 workstation in the direction of the worker (window direction),

 so the filter replacement is not possible

If it is not done regularly, it may cause contamination of the

 experimental sample or cause infection of the worker

It's more important than anything else To proceed with the

 filter replacement, measure the specifications of the filter accurately in advance

It is important to proceed with the replacement. If you use a filter that doesn't

 meet the specifications, there will be a gap between the device and the filter

There is a risk that unrefined air may permeate and contaminate the sample.

In the case of domestic equipment, the filter size is often unknown

 because the manufacturer or model name is not accurate

Alpha Line Lab Business conducts preliminary measurements when replacing all filters

After measuring the size, we will manufacture and replace the filter.

If you don't have any information about the equipment, please feel free to 

contact us for filter replacement!

 

<HEPA Filter>

The HEPA filter is a key factor in determining the cleanliness of the clean bench.

The filter was black when it was time to replace it, but when the 

particles were piled up enough to change color

The replacement cycle must be observed as the air filter is completely 

blocked, resulting in loss of function and reduced wind

 speed, which increases the risk of contamination.

The HEPA filter used as the main filter stands for high-efficiency particulate 

air filter, and is more than 0.3 (micrometer) size floating in the atmosphere

It is a high-performance air purification filter that removes 99.95% 

of particles. Most of the bacteria under 2.5μm of ultrafine dust are 1 to 5μm in size

Removal is possible through the HEPA filter. If you maintain a normal 

level of work, the maximum life expectancy is about two years

The lifespan may vary depending on the cleanliness of the 

facility, the content of the experiment, and the frequency of use.

Therefore, considering these factors, it is usually recommended to replace once a year.

 

 

<Pre Filter>

A pre-filter mounted on the air inlet face of the clean bench.
 
​The pre-filter was also contaminated enough to be checked
 
 with the naked eye, but if you leave the contaminated filter unattended
 
​Particles clogged filters can interfere with the flow of air,
 
 overload the internal motor, causing a clean bench failure.
 
Therefore, it is necessary to proceed with the replacement 
 
of the pre-filter through periodic inspection.
 
The pre-filter is a primary filtration filter that filters out more 
 
contaminants than the hepa filter, so it is recommended to
 
 replace it more often than the hepa filter.
 
​(The prefilter removes particles larger than 10 to 30 that can
 
 directly harm the human body and samples, 
 
such as dust or floating mull in the atmosphere.)
 
The replacement cycle is fast, so it is recommended to use 
 
it once a year from 6 months to 1 year (800 to 1000 hours).

 

<Simple Validation>

Alpha Line Lab Business provides a free signature service

when replacing a clean bench filter or cleaning care

Simple validation is provided free of charge. Simple validation is

 a device that's capable of delivering results that meet the set values

Consistent derivation, verification, measurement, documentation, 

and delivery through professional equipment and personnel

Simple validation is based on the same IQ qualification assessment as the paid validation

Measure verification. The report can be used for internal 

equipment management and cannot be submitted outside.

 

Once the work is completed, the work history will be attached to the equipment.

Anyone can easily check the management history even 

if the person in charge of equipment management changes

We will give you a unique number, so we will help you 

manage it systematically in the future.

All fieldwork for the Alpha Line Lab business is done by a 

professional, skilled and experienced field manager

Accompanied by the Safety Guide Manual and supervised the site.

Alpha Line Lab Business is a 29-year laboratory-related experience

 company and through many years of know-how and technology

We offer the best solution that always puts your safety first.
