Explosion Proof Shale Shaker vs Standard Shale Shaker

Choosing between an explosion-proof and a standard shale shaker requires understanding the fundamental differences in design, certification, cost, and application suitability. This comparison helps drilling contractors make informed equipment decisions for their specific operational requirements.

Design and Component Differences

The primary difference between explosion-proof and standard shale shakers lies in the electrical design. Standard shakers use conventional motors and electrical components that may produce sparks during normal operation, such as from brush-type motors, switch contacts, or connection terminations. Explosion-proof models from Aipu use certified flameproof enclosures around every electrical component, preventing any internal spark or flame from reaching the surrounding atmosphere. The vibrating motors supplied by Ital-Vibras, Martin, or Oli for explosion-proof units are specially certified variants with temperature-limited windings and flameproof terminal boxes. Cable entries use certified explosion-proof glands that maintain enclosure integrity while accommodating power and control wiring. Junction boxes are sealed with flame paths that cool escaping gases below ignition temperature before they reach the external atmosphere. These design differences add material and labor costs to the manufacturing process, which is reflected in the higher purchase price of explosion-proof equipment compared to standard shakers with the same 50 to 420 cubic meters per hour flow capacity.

Certification and Documentation

Explosion-proof shale shakers carry formal third-party certifications (ATEX and IECEx) that standard shakers lack. Each certified unit receives a unique marking plate identifying its category, gas group, temperature class, and certifying body. Comprehensive technical files documenting design, testing, and production quality control accompany each certified shaker. Aipu maintains these records as part of its API Q1 and ISO 9001 certified quality management system. Standard shakers do not require this level of documentation, simplifying the purchasing process but limiting deployment options in classified hazardous areas. For operators working in multiple jurisdictions, the portability of ATEX and IECEx certifications across regulatory frameworks provides deployment flexibility that justifies the additional investment. Aipu’s 15-plus years of manufacturing experience and installations in more than 30 countries support the consistent delivery of both certified and standard shaker configurations.

Application Selection Criteria

The decision to specify explosion-proof or standard shakers depends primarily on the hazardous area classification of the drilling location. If the solids control area is classified as Zone 1 or Zone 2, explosion-proof equipment is mandatory by regulation and safety practice. For locations without hazardous area classification, standard shakers from the Aipu Hunter series remain the cost-effective choice, delivering the same 6.0G to 7.5G vibration performance and adjustable deck angle from negative one degree to positive five degrees. Some operators choose explosion-proof shakers even in unclassified areas as part of a conservative safety policy or for fleet standardization across multiple rig types. Aipu’s 50,000-square-meter Xi’an facility manufactures both configurations, allowing customers to select the appropriate equipment for each application while benefiting from the common design platform, spare parts, and after-sales support. The ISO 14001 environmental certification and ISO 45001 occupational health and safety certification apply equally to both product lines, reflecting Aipu’s consistent commitment to responsible manufacturing regardless of product certification level.
