COM.SAR IT Cleaning

HEPA air cleaning and climate monitoring

We use mobile HEPA H14 air cleaners and, where commissioned, check temperature, humidity and particle levels during operation and construction.

Air cleaning & climate control

Review room air alongside equipment needs

We review dust levels, accessible air paths and your equipment requirements, alongside temperature and humidity. Existing readings are discussed with your team. Manufacturer specifications and site conditions remain the basis for assessment.

Mobile HEPA H14 air cleaning

Our portable units filter particle-laden air in server rooms, data centers and technical areas. Position and run time are planned for the room. Dust already deposited on surfaces and inside equipment needs separate cleaning.

During and after construction

Portable air cleaning can support cleaning and decontamination after construction-dust ingress. We coordinate separation, airflow and surface cleaning. Particle checks before, during or after the work can be agreed in addition.

Filtered supply air for positive-pressure zones

Enclosed racks or separated equipment areas can be supplied with HEPA-filtered air. Unit design, air volume, pressure and operating mode must suit the application. We agree checks for temperature, air supply, filter condition and pressure throughout use.

What the filter specification means

We use H14 HEPA filters. The supplied unit specification states 99.995% efficiency at 0.3 µm under a DOP test at 100 CFM. This is a result for the stated test conditions, not a room-wide cleanliness guarantee. Room volume, contamination, airflow, filter condition and run time also matter in use.

Measure in the right places

One room reading does not show conditions everywhere around the equipment. Where commissioned, we review existing data or measure at agreed points such as rack air inlets or inside a protected zone. Temperature and humidity are assessed against equipment requirements; differences and changes are recorded.

Check particles, filters and air paths

Visual checks reveal deposits on surfaces, filters and accessible air paths. Particle measurements can supplement this review. We agree sampling points, conditions and assessment criteria first. Raised floors, supply and return areas and CRAH surroundings may also be included.

Follow changes during construction

Opened access points, new work and changed airflow can affect a protected area. We establish what is checked, how often and who is notified about deviations. For positive-pressure zones, agreed pressure conditions and temperature are included.

Results and follow-up

The report records measurement locations, times, conditions, values and observations. We then discuss cleaning, specialist assessment or further checks with you. Continuous monitoring requires a separate agreement on equipment, review and response. Technical HVAC maintenance and control changes remain with the relevant specialists.

FROM ASSESSMENT TO HANDOVER

Assess conditions. Identify changes.

  1. 01

    Clarify requirements

    We discuss equipment, room design, existing readings and the reason for the assessment.

  2. 02

    Agree the scope

    Together, we define relevant areas, measurement points, time periods and responsibilities.

  3. 03

    Inspect and assess

    Agreed checks and measurements are reviewed against site requirements.

  4. 04

    Document and follow up

    You receive results, observations and coordinated next steps.

GOOD TO KNOW

Air cleaning and climate control: your questions

Discuss your requirements
When is mobile air cleaning useful?

For example, during construction, following construction-dust ingress or alongside decontamination. Deployment is planned around the room, contamination and airflow. Removal of settled contamination is also considered.

Which filters are used?

We use HEPA H14 filters. Equipment selection and sizing reflect the area and intended operating mode.

Which conditions are checked?

Depending on the project, we consider temperature, humidity and visible dust contamination. Particle measurements and pressure checks within positive-pressure zones can be agreed additionally.

What temperature and humidity values are appropriate?

Assessment follows manufacturer guidance, installation design and operating requirements. Relevant specifications and measurement points are therefore agreed for your site.

Can checks take place during live operations?

Many environmental checks can take place with IT running. Access, measurement locations and procedures are agreed with responsible personnel. Equipment interventions are included only when expressly agreed and approved.

Can checks be carried out during construction?

Yes. Scope and frequency can be tailored to the construction phase. For temporary positive-pressure zones, temperature, air supply and agreed pressure conditions are also considered.

Does COM.SAR IT Cleaning also carry out technical cooling maintenance?

The precise scope is agreed for each project. Cleaning and inspection activities are coordinated with the responsible cooling and installation specialists. Technical servicing or control changes require separate agreement.

Will I receive a measurement report?

Agreed records may cover measurement locations, conditions, timing, readings and observations. Scope, recipients and follow-up checks are established in advance.
