Source-capture configurations
Laboratory Exhaust Hoods
Exhaust hoods provide project-specific source-capture positions above or around a task. Hood geometry, capture distance, airflow, duct route, fan, controls, discharge, and room air balance must be established by the responsible engineering and safety teams.
Final materials, dimensions, performance requirements, and compliance criteria must be confirmed in the quotation and technical review.

Product planning
Decisions that shape the final configuration
Use these planning points to organize the room, equipment, service, and operating information needed before a configuration is confirmed.
Describe the source
Document what is released, where it is generated, release direction, temperature, task duration, operator position, and obstacles between the source and the proposed hood.
Treat capture as an engineered system
Hood selection must be coordinated with airflow, duct losses, fan selection, controls, make-up air, discharge, noise, and local requirements. A product photograph is not a ventilation design.
Confirm mounting and service access
Provide ceiling structure, bench or equipment dimensions, suspension points, duct connection, maintenance route, electrical needs, and cleaning access before technical approval.
Technical brief
Configuration details to confirm
These fields provide a practical review framework rather than fixed model claims. Record the agreed selection in the quotation, drawings, and technical submittal before production.
- Reference formats
- The source brochure shows suspended canopy, steel bench-top, PP bench-top, and paired linked exhaust-hood configurations.
- Enclosure
- Body material, liner, opening, sash or screen, access panels, and surface finish are selected for the confirmed process and cleaning conditions.
- Capture geometry
- Hood width, depth, height, mounting distance, side containment, operator position, and source relationship require engineering review.
- Exhaust interface
- Duct connection, design airflow, pressure loss, fan and control responsibility, discharge route, and make-up air are project inputs.
- Electrical and controls
- Lighting, sockets, control panels, monitoring provisions, voltage, plug or hard-wire method, and destination requirements are confirmed in the technical schedule.
- Required submittals
- Provide the process brief, source dimensions, room or ceiling plan, mounting height, duct design status, utilities, destination, and responsible engineering criteria.
Reference model guide
YOJIA inquiry models and reference parameters
Use these original YOJIA reference codes to compare common configurations and prepare an inquiry. They are planning identifiers, not copies of another manufacturer's models or fixed production guarantees.
| Reference model | Configuration | Reference dimensions | Selection notes |
|---|---|---|---|
YJ-EH-1200-W | Wall-mounted exhaust hood | 1200 × 800 × 600 mm | Reference capture hood above a defined heat, vapour, or process source. |
YJ-EH-1500-W | Wall-mounted exhaust hood | 1500 × 800 × 600 mm | Wider wall position; overhang and mounting height follow the source geometry. |
YJ-CH-1500-C | Ceiling-suspended canopy hood | 1500 × 1000 × 500 mm | Suspended reference for suitable non-enclosed sources after engineering review. |
YJ-AH-075 | Local articulated extraction arm | 75 mm nominal connection | Point-capture reference; reach, joint resistance, hose, and airflow are project-defined. |
Reference parameter range
- Reference widths
- 1200 and 1500 mm hood modules; source width, overhang, mounting height, obstructions, and access determine final size.
- Construction
- Steel, stainless steel, or PP can be discussed after the source, temperature, vapour, cleaning, and corrosion conditions are known.
- Mounting
- Wall, ceiling, bench, or articulated mounting requires verified support, clearances, and maintenance access.
- Capture limitation
- A canopy or local arm is not a substitute for an enclosed fume hood where containment or a physical barrier is required.
- Ventilation scope
- Capture criteria, airflow, duct size, fan, controls, discharge, make-up air, noise, and commissioning belong to the project ventilation design.
- Ordering rule
- The reference dimensions do not establish capture performance. Release follows approved ventilation inputs and installation details.
All dimensions are nominal planning references. Final materials, thicknesses, loads, ventilation criteria, fixtures, interfaces, compliance evidence, and supplied scope must be recorded in the approved quotation and technical documents.

Buyer questions
Before requesting a quotation
Clear project inputs help the team identify the right configuration and the details still requiring technical review.
01Is an exhaust hood the same as a laboratory fume hood?
Not necessarily. A source-capture hood and an enclosed fume hood have different geometry and containment behavior. The responsible project team should select the approach from the actual process and risk review.
02Can airflow be selected from the product width alone?
No. Source behavior, capture distance, enclosure, cross-drafts, duct losses, room air balance, and applicable criteria all affect the engineering decision.
03What is needed for a canopy-hood inquiry?
Provide the equipment or source dimensions, emission description, mounting height, ceiling structure, proposed duct route, room plan, operating schedule, and the engineer responsible for airflow and discharge.
