Difference between SEALED HEPA and HEPA
Hepa vacuums are used in several applications and there are differences in filters and units used that are considered to vary in safety ratings. A sealed hepa versus a regular hepa will entail that the system is sealed and contaminants will not be able to escape. Certain factors will determine that a sealed hepa unit is the mandatory application needed to remove hazardous materials safely. The filter most often used will be a hepa standard and the sealed rating will apply to the equipment that is using the filters in operations. Operations that would include the use of hepa filters are vacuums and air purifications systems.
Systems using a filter will provide several applications that can be used in residential, commercial and industrial applications. One of the most common applications a of a sealed hepa system will be to remove toxic and dangerous air particulates. A hepa system is rated as a high proficiency rated air purification module. A sealed system while using specific filters will provide that the hazardous material will not escape the system is used in cleaning and air purification. Examples of toxic materials such as lead based paints that are required to be removed from residential and commercial operations will be regulated that a sealed system is used in the removal and cleaning of theses areas.
An important factor of a sealed unit when in use under hazardous conditions may have several various guidelines in operating tactics to insure that the removal of particulates follow such mandates. Removing lead based paints can create dusts of lead particulates and may necessitate the use of a wet/dry hepa vacuum system. Under strict regulations the dust caused by removal will contain hazardous lead particles and if inhaled can create several severe health symptoms and death. A sealed unit will require that specific steps are followed and the area is washed, stripped and cleaned again. The vacuum units used will need to be sealed in all areas and the feature of attachments that close when the unit is powered down will be necessary. It is possible to cover the open intake ports with tape before powering down to ensure that all particulates are sealed with in the unit.
Cleaning a unit will be necessary at times of operation and after. Cleaning procedures will be varied due to the conditions of particulates and warranted possible hazards. If one is removing toxic hazardous chemicals, special bags or liners may be necessary to use in a sealed unit to dispose of waste safely and not contaminant the clean area. It is possible that the debris will be collected or placed in a separate area or facility than normal debris and should never be thrown in the trash. In industrial applications there will be a department that will handle waste removal and are certified to operate hepa equipment and dispose of hazardous particulates safely.
A sealed hepa unit will have features that protect and integrate the unit from exposing hazardous materials. Gaskets and sealants used to secure the unit will be specific to the variable units and contaminants that the unit is specifically operated to remove. Performing regular maintenance and services to the units is enforced and parts and steps used in the process will be mandated. Applications of servicing a unit may be necessary to incorporate a certified technician to ensure that are guidelines are safely met and parts used are with in the regulated guidelines per the unit manufacturers specifications. Sealed units will be closely monitored and tested in regular intervals to ensure that the guidelines are followed.
In industrial applications if a unit is not used and maintained with in manufacturer and safety guidelines. It is possible that it could cause a backlash in which not only workers and the environment could be contaminated but that the operations could be stopped until the units are brought up to code. Safety guidelines are regulated by state and government offices with strict specifications for the amount of pollutants an individual can safely be exposed to and sealed units operating under hepa guidelines will aid in adhering to these strict guidelines.
In air purification systems such as hospitals and airplanes there are several specifications in which a sealed hepa unit will be necessary and the guidelines will also be as strict as in some hazardous comparisons. Hospitals are a generalized area that can carry a variety of harmful pollutants and the systems will use several hepa systems in conjunction with a sealed unit to create the purest conditions possible and keep contaminants from recirculation. In epidemic proportions, sealed systems can also be used to recirculate and purify air in quarantine situations by government mandated health branches.
