Filter cabinets Installation in Mission, BC

Installing a properly specified filter cabinet is a critical investment for industrial and commercial HVAC and particulate control systems. In Mission, BC, where moisture, seasonal wood smoke, and a mix of light industry and commercial facilities create variable airborne particulate loads, a correctly sized and installed filter cabinet protects equipment, improves indoor air quality, and ensures regulatory compliance. This page explains the cabinet types, how we assess and size cabinets for airflow and filtration needs, the installation and commissioning process, safety and code considerations, recommended filter media and maintenance practices, typical timelines, and what to prepare when requesting a professional assessment.

Common filter cabinet types and where they are used

Understanding cabinet types clarifies which solution fits your facility needs in Mission, BC.

• Panel filter cabinets
• Use flat panel or pleated panel filters (typical for general HVAC and building protection).
• Best for offices, retail, and tenant spaces with moderate particulate loads.
• Bag filter cabinets
• Accept deep-pleat or pocket filters for higher dust-holding capacity.
• Common in light manufacturing, paint booths, and areas with seasonal agricultural dust.
• HEPA / microfilter cabinets
• Designed for high-efficiency media delivering 99.97% efficiency at 0.3 microns or better.
• Required for cleanrooms, laboratories, medical facilities, and sensitive process areas.
• Multi-stage cabinets
• Combine prefilters, intermediate stages, and final HEPA/microfilters in one housing.
• Ideal for challenging environments where long media life and high final efficiency are needed.

How we assess and size a cabinet for airflow and filtration needs

A correct cabinet selection starts with site-specific data. Key evaluation steps include:

• Review facility use and contamination sources: woodworking dust, food processing, vehicle emissions, seasonal wood smoke.
• Measure or obtain design airflow (CFM) and duct dimensions.
• Calculate required face velocity and media area to meet target pressure drop and filter life.
• Determine final efficiency requirements (MERV rating or HEPA class) based on occupant safety, process control, or regulatory mandates.
• Check fan capacity and system static pressure to ensure the selected cabinet and media do not cause unacceptable reductions in airflow.
• Confirm structural supports, access space for maintenance, and any required airtight flanges or gaskets.

Sizing aims to balance low face velocity for longer filter life with acceptable pressure drop that the fan system can support.

Step-by-step installation process and site preparation

Proper site prep avoids delays and ensures safe, code-compliant work.

• Site preparation
• Clear staging area and provide safe access to duct and mechanical rooms.
• Confirm power isolation points, hoisting access for heavy cabinets, and scaffold or lift requirements.
• Provide as-built drawings and existing fan curves when available.
• Installation steps

1. Shut down affected HVAC zone and follow lock-out/tag-out procedures.
2. Isolate and remove existing filters and housings as required.
3. Position cabinet, set and level on support structure, and seal structural penetrations.
4. Connect ducts with airtight flanges or flexible connections to prevent bypass.
5. Install access doors, sight glasses, and safety hardware per design.
6. Install filter media with proper orientation, gaskets, and retention clips.
7. Reconnect controls, differential pressure sensors, and any bypass dampers.
8. Verify electrical and control wiring for fans and sensors.
9. Return system to service for commissioning.

Safety and compliance considerations

Installations must adhere to local and national codes and to safe work practices.

• Regulatory references
• Work in accordance with the BC Building Code and applicable CSA standards for HVAC and filtration equipment.
• Follow WorkSafeBC requirements for fall protection and confined space when required.
• On-site safety
• Enforce lock-out/tag-out and respiratory protection when replacing high-load filters.
• Implement containment and negative pressure during filter change-outs where hazardous dust is present.
• Ensure cabinet access panels are secured and labeled for safe operation.

Recommended filter media and performance specifications

Select media based on particle size, contaminant type, and equipment limits.

• Typical media recommendations
• Prefilters: MERV 6 to 8 for coarse dust and to protect downstream media.
• Intermediate filters: MERV 11 to 13 for fine particles and allergen control.
• Final filters: HEPA/ULPA where required for sterile or sensitive processes, targeting 99.97% efficiency at 0.3 microns for HEPA.
• Bag filters: deep-pleat or pocket media where high dust loads shorten panel life.
• Performance specs to confirm
• Initial and final pressure drop ratings.
• Dust holding capacity and recommended service life.
• Sealing method to prevent bypass at joints and doors.
• Media compatibility with humidity and chemical exposures typical of Mission facilities.

Commissioning and testing procedures

Commissioning proves the system meets design targets and provides documented performance.

• Pre-start checks: verify cabinet installation, control wiring, and sensor calibration.
• Airflow verification: measure system CFM and compare to design values; check fan curves.
• Differential pressure: record clean filter pressure drop and target alarm setpoints for change-out.
• Filter integrity and leak testing: for HEPA systems perform particle count testing or photometer based integrity tests to verify no bypass or leaks.
• Final balancing: adjust dampers and controls so each zone receives specified airflow.

Routine maintenance and replacement schedules

Maintenance preserves performance and extends media life.

• Suggested schedule (adjust based on local loads and monitoring)
• Visual inspection monthly for dust loading and gasket integrity.
• Differential pressure checks monthly to quarterly.
• Prefilter replacement typically every 3 to 12 months depending on loading.
• HEPA final media inspected annually and integrity tested at least annually for critical areas.
• Keep spare filter inventory and record keeping for asset management.
• Simple maintenance actions
• Replace filters before pressure drop forces fans to work inefficiently.
• Maintain good cabinet seals and fastener torque.
• Keep surrounding areas clean to prevent reintroduction of contaminants during service.

Warranty, service plans, and typical project timelines

Choose warranties and support that match risk tolerance and operational needs.

• Warranties and service
• Manufacturer warranties typically cover structural integrity and media performance; confirm exclusions for misuse or improper maintenance.
• Service plans usually include scheduled maintenance, priority response for emergencies, and documented filter lifecycle tracking.
• Typical timelines
• Simple filter cabinet swap: 1 day when access is straightforward.
• New cabinet with minor duct modifications: 2 to 5 days.
• Full multi-stage installation with control integration or cleanroom connections: 2 to 6 weeks, including design, procurement, and commissioning.
• Example project snapshots (anonymized)
• Light manufacturing retrofit: replaced panel-to-bag cabinet to manage increased sanding dust; installation and commissioning completed in 4 days with immediate reduction in downstream coil fouling.
• Medical lab upgrade: installed multi-stage cabinet with HEPA final and performed integrity testing; project spanned 3 weeks to accommodate custom duct transitions and commissioning.

Preparing to request a quote or assessment

When seeking proposals, gathering the right information speeds accurate estimates.

• What to provide to contractors or assessors
• Facility address and mechanical room access constraints.
• Existing HVAC drawings or photos of current filter housings and ductwork.
• Design airflow or system CFM, fan curves if available.
• Description of contamination sources and any regulatory or process air quality targets.
• Desired timelines and any operational shutdown windows.

Providing this information lets a contractor produce a scoped, accurate assessment and equipment specification tailored to Mission, BC conditions, ensuring a durable, code-compliant filter cabinet installation that meets your facility performance needs.
